Big Idea

The argument in one line.

The restlessness and dissatisfaction that define modern life are not personal failings but biological signals: human brains and bodies evolved for friction-rich environments, and the systematic removal of challenge leaves us literally under-stimulated.

Who This Is For

Read if. Skip if.

READ IF YOU ARE…
  • You feel vaguely dissatisfied despite your life looking good on paper and cannot explain why.
  • You have tried willpower-based habit systems repeatedly and they keep breaking down.
  • You are curious why people voluntarily sign up for cold plunges, hyrox races, and 75 Hard.
  • You want a science-grounded explanation for cognitive decline you have noticed since AI tools became daily habits.
  • You are a parent, teacher, or manager wondering why the people around you seem less resilient than they used to be.
SKIP IF…
  • You are already training hard, have low screen time, and feel cognitively sharp.
  • You want a quick motivational hit; this runs 22 minutes and moves at an educational pace.
TL;DR

The full version, fast.

Hunter-gatherer ancestors walked 16,000 steps daily and solved survival problems constantly; modern adults walk 4,000 steps and outsource thinking to AI. The gap between the friction our bodies evolved to expect and the frictionless lives we have built is the root cause of widespread restlessness, cognitive decline, and burnout. The author calls this friction starvation. The fix is not willpower but identity: choosing to be someone built for friction, then engineering it back in across four domains: physical challenge, sensory silence, cognitive effort, and deep social investment.

Atomic Insights

Lines worth screenshotting.

  • Our entire generation is friction starved: we removed effort faster than evolution could adapt.
  • Hunter-gatherer ancestors walked 16,000 steps a day; the modern adult walks 4,000 and outsources thinking to AI.
  • What we call laziness is one of the most ancient survival instincts humans have: the problem is we built a world where it works against us.
  • Neuroplasticity works in both directions: you either use your brain or it adapts down to the level of effort you give it.
  • London taxi drivers who memorized 25,000 streets had measurably larger hippocampi, and the longer they drove, the bigger it grew.
  • Only 2% of people take the stairs over the escalator when given the choice.
  • Meaningful neuroplastic change requires meaningful challenge: the brain only rewires itself when the work is hard enough that existing pathways cannot handle it.
  • Changing outcomes or processes fails long-term because the identity underneath never shifted.
  • The default mode network only switches on when you are not focused on a task: constant stimulation starves the process that consolidates memory and generates creative insight.
  • Everyone wants a village but no one wants to be a villager: adult community requires active construction, not passive inheritance.
  • 80% of New Year resolutions die by February not from personal failing but because willpower is the wrong mechanism.
  • Hormesis: small repeated doses of stress make a biological system stronger. Your muscles, neurons, and cardiovascular system all follow this rule.
  • Writing first and refining with AI second is the difference between using AI as a tool and using it as a replacement for thinking.
  • The identity vote is a small moment: stairs or escalator, staring out the window or reaching for your phone. Each choice compounds into who you become.
  • Not all friction is worth keeping. Email admin is just tax. The question is whether the friction builds you or depletes you.
Takeaway

Your brain grows toward what you ask of it.

WHAT TO LEARN

Modern comfort is not neutral: it is a slow downgrade of both physical and mental capacity, and reversing it starts with identity, not discipline.

02Why Our Brains and Bodies Need Challenge
  • Hunter-gatherer ancestors took 16,000 steps per day; modern adults average 4,000 and the comfort gap arrived faster than evolution could track.
  • Hormesis is the mechanism: small repeated stressors make biological systems stronger, not weaker. Removing all stress removes the signal to adapt.
03Do Taxi Drivers Really Have Bigger Brains?
  • London taxi drivers who memorized 25,000 streets showed measurably larger posterior hippocampi, and the longer they drove, the larger the region grew.
  • Neurons that fire together wire together: repeated cognitive effort strengthens specific pathways, making them faster and more automatic over time.
04Rewiring Your Identity
  • Outcome and process goals fail at high rates because the underlying identity never shifted.
  • Identity-level reframes make individual choices feel like natural expressions of who you are rather than acts of willpower.
07Sensory Friction
  • The default mode network only activates during unstimulated time and this is when memory consolidates and creative connections form.
  • Checking a phone in every idle moment prevents the brain from doing some of its most important maintenance work; boredom is process time, not waste.
08Cognitive Friction
  • Writing your own answer before consulting AI keeps your synapses in the loop; the comparison step itself is where learning happens.
  • Thirty minutes of uninterrupted single-task focus is becoming rare enough to be a competitive advantage and the capacity must be practiced to be retained.
09Social Friction
  • Adult friendships require someone to act as chief of the village: the person who sends the actual invite rather than the vague suggestion to hang out.
  • Saying the harder, more honest thing in a conversation is a form of social investment that shallow screen-mediated connection has made less common and more valuable.
Glossary

Terms worth knowing.

Friction starvation
A coined term for chronic biological under-stimulation caused by modern convenience engineering away the physical, cognitive, and social demands that human biology evolved to expect.
Evolutionary mismatch
The gap between the environment an organism evolved for and the one it currently inhabits. Used here to explain why modern comfort produces anxiety and cognitive decline rather than wellbeing.
Hormesis
A biological principle where small, repeated doses of stress produce an adaptive response that makes the system stronger over time. Applied to muscles, cardiovascular health, and cognitive performance.
Neuroplasticity
The brain ability to physically reorganize itself in response to use: forming new neural connections, strengthening existing ones, and even growing tissue in regions under sustained cognitive demand.
Hebb Law
A 1949 neuroscience principle: neurons that fire together wire together. Repeated co-activation of neurons strengthens the synaptic connection, making the pathway faster and more automatic.
Default mode network
A brain network that activates specifically when a person is not focused on an external task. Associated with memory consolidation, emotional processing, and creative insight. Suppressed by constant stimulation.
Posterior hippocampus
The rear portion of the hippocampus, associated with spatial memory. London taxi drivers in the Maguire 2000 study showed larger posterior hippocampi than non-drivers, with volume correlating to years of experience.

00:00Our hunter gatherer ancestors walked around 16,000 steps a day, hunted their own food, and built things with their bare hands. Then you have the average modern adult who walks four times less, sits for nearly ten hours a day, and increasingly outsource outsource our thinking to AI.
00:14So I have a slightly embarrassing confession to make. My life has gotten too comfortable, and I'm not enjoying it. A lot of us are feeling anxious or restless, dissatisfied, feeling purposeless, or burned out, or even just feeling kind of flat.
00:25And it seems like the more comfort that we add in, the worse it gets. Because we were actually never built for frictionless lives like this. And so it's no wonder that we're finding it hard to do hard things because we're just not used to it anymore.
00:37And my whole take on this is that our entire generation is basically friction stuff. If you're new here, I'm Izzy. I'm a mom, tech cofounder, and Cambridge trained doctor.
00:44And on this channel, we explore the strategies and mindsets to help you create a life that you love. So in this video, we'll walk through understanding the science behind why our bodies and brains need challenge to grow. The identity shift that gets your brain to actually crave hard work, and four specific kinds of friction that are actually worth engineering back into your life so you can do the very things that you were built for.
01:03Also, quick thing as a companion to this video, I've made a completely free friction audit guide, and you can find that down below in the description. So without further ado, let's dive in. So firstly, the science.
01:15You might think you're lazy, but according to evolutionary biology, that's pretty much the furthest thing from the truth. We were literally built to do hard things, and here's the science behind it. During my time at Cambridge, I spent one year studying biological anthropology, essentially studying human biology and evolution over hundreds of thousands or millions of years.
01:31And for almost all of human history, our ancestors lived in environments where being physically and cognitively challenged was the only way to stay alive. Movement, effort, problem solving, navigation, memory, building relationships, skills, these were all structural features of being alive and surviving.
01:48They weren't optional add ons. And so for the last two hundred thousand years of human existence, no one ever intentionally exercised because they didn't need to.
01:56Life naturally supplied the friction and the exercise that they needed. And genuinely, both you and my ancestors would probably scoff at a high rocks. Even just a few generations ago, so for example, my grandma's generation in China, they find it confusing as to why people actively pay money to a personal trainer to be made to exercise.
02:14Because for many of them, movement and farming and lifting things and carrying things was just a natural part of daily life. Obviously, in younger generations, exercise and working out is emerging as more of a status symbol and a health forward symbol in modern China and younger people in China.
02:28And so this is a timeline just from two hundred thousand years ago, which is when anatomically modern humans were thought to be around. Essentially, humans pretty much like you and I today evolved and were roaming around and living their lives. For the vast majority of the time, they lived as hunter gatherers, living in small tribes and villages, hunting and gathering, sometimes doing a little bit of gardening, that kind thing.
02:47Only about ten thousand years ago did organized agriculture become a thing, allowing bigger cities of people to coalesce and start building stuff together. Then just one hundred and fifty years ago, we had the industrial revolution. Thirty years ago, we invented the Internet.
03:01And then just in the last couple of years, AI has really been taking off. And so you can see how for the vast majority of our evolutionary history, we didn't have things like the Internet, technology, industry, AI.
03:12All of these kinds of things were not available to us. And so our bodies and brains didn't evolve to be optimal under these conditions. All of the engineering away of the environment and the frictions that we were used to happened in a very, very tiny sliver of time in the last hundred years or so.
03:27Anthropologists studying modern hunter gatherer communities like the Hadza in Tanzania, whose lifestyle broadly resembles how we think our ancestors probably lived, did studies measuring their daily activity. On average, the Hadza take about 16,000 steps a day versus the modern adult takes around 4,000 to 5,000 steps a day.
03:44And there's a name for this. It's called evolutionary mismatch, where the environment and lifestyle that we evolved for no longer matches the reality that we're actually in.
03:52In biology and medical science, hormesis is a word that describes how small repeated doses of stress can actually make a biological system stronger over time. And this is exactly the principle that underlies exactly why this loss of friction is causing us to feel more unbalanced than ever. An example of hormesis is when you lift heavy weights, you actually cause micro tears and micro damage to your muscles, which in the short term technically makes them weaker.
04:17Because over the course of a weight lifting session, you can actually lift less and less weight because your muscles start to accrue a little bit of damage. But then ultimately, this stimulus of some stress and damage and weakening actually triggers your muscles to rebuild even stronger. Doctor Mark Matson, who used to be the chief of the laboratory of neurosciences at the National Institute on Aging, has spent decades researching exactly this, showing how hormetic stressors trigger those adaptive responses that keep your cells healthy and can even prevent or slow down things like memory loss, neurodegeneration, and metabolic diseases.
04:47Ultimately, our bodies don't just tolerate effort. They actually need it to function the way that they were designed to, and the same principle applies to our brains. And the core principle that brains grow under challenge is actually one of the most established findings in modern neuroscience.
05:01It's something called neuroplasticity. Neuroplasticity can be defined as the brain's ability to physically reorganize itself in response to use, forming new connections, strengthening existing ones, and even growing new tissue and regions that are being challenged. And critically for neuroplasticity, meaningful change requires meaningful challenge because the brain only puts in the effort to rewire itself in a significant way when the work is actually hard enough that the existing pathways can't quite handle it.
05:25And here's one of my favorite examples of neuroplasticity in real life. In 2000, a neuroscientist at UCL called Eleanor Maguire and her team published a really cool study.
05:34They recruited a cohort of London taxi drivers. And a bit of fun context if you don't know, to get a license to drive a black cab in London, you have to pass this mega test called the knowledge. To pass the knowledge, you need to memorize about 25,000 streets and thousands of landmarks across the entire city.
05:51And it actually takes most drivers three or four years of studying and taking the test to actually pass it. And what they found in this study was the part of the taxi driver's brains that handles spatial memory called the posterior hippocampus was actually measurably bigger in volume compared to non cabbies. And the longer that they had been driving, the bigger this region of their brain actually was.
06:09And, essentially, what they found was the cognitive work of constantly memorizing, recalling, and using this knowledge of all the streets was literally physically growing this part of their brains. And as well as growing the volume, this active recall strengthens connections between neurons, which links to the principle of Hebbian plasticity, which we used to study back in medical school.
06:25Back in 1949, a psychologist called Donald Hebb came up with what's known as Hebb's law, which is that neurons that fire together wire together. So our brains are actually not fixed even as an adult.
06:36They constantly change, reform, reshape, create new connections, prune old ones in response to the cognitive stimuli that we get in our day to day lives. And so it's kind of a bit like training a muscle where the more reps reps of cognitive work that you give your brain, the stronger, more efficient, higher performance you actually get from it.
06:51But then coming back to this comfort crisis, modern life has actually engineered most of that cognitive tension out. Maps navigate for us, search engines remember things for us, AI now even just thinks for us and tells us what we should do and think. And so our brains can actually be very, very chill and do very little to survive.
07:08The ultimate result of this is that if we go with the flow and lean into what's comfortable, both our physical and mental faculties are downgrading at the same time. Not because we're broken, but because we're adaptable, and we're learning to adapt to a world that we actually were never designed for. And so this is the concept I think we need to talk about more, which is friction starvation.
07:26I think that the phenomenon of actually actively removing friction from our modern life deserves actually a name because nothing in mainstream culture has actually given it one yet, so this is just a name that I've come up with. And this is how I'd explain it. Because our brains and bodies no longer receive the effort signals that we evolved to expect, we paradoxically feel worse as we layer on more and more comforts.
07:46In his book, The Comfort Crisis, Michael Easter described something quite similar. And here's something I've noticed over the last couple years on social media. And especially if you're in your late twenties or early thirties like I am, you might notice that when you open Instagram or social media, you notice loads of people doing high rockers, people doing London marathons, people talking about their cold plunges, dry January, 75 hard, ultra weekends, and Lake District.
08:06And interestingly, several years ago, nobody really talks about any of this outside of specific niches. But now people really enjoy sharing about the versions of hard that they have voluntarily signed up for. And I think some of this isn't just to do with fitness.
08:19It's also to do with us wanting to find something to really challenge ourselves again. It's this yearning that people are feeling to almost counteract to this comfort crisis that we find ourselves in. By pushing ourselves to do something hard, we actually feel great.
08:31Our body releases endorphins and feel good neurochemicals in response to a hard stressor that we expose ourselves to. And so once we understand frictional salvation and the science behind it, we can start to address it and fix it. But this only works if we're trying to fix it at the level that the problem is actually operating at.
08:46And this is something I actually learned the hard way this year, and it's that just changing behavior doesn't really reach the root. The level we need to work on is actually identity. Because when we don't choose to do hard things and we choose to take the easy way, it isn't because we're lazy or lack willpower and should judge ourselves negatively for this.
09:01Because the honest truth is that your body is just doing exactly what evolution designed it to do, which is to be energy efficient. For nearly all of human history, food was scarce and effort was costly. So the brains and bodies that survived were those that took the easiest path which was most efficient.
09:17And so what we sometimes call laziness and view in a negative light is actually one of the most ancient and well developed survival instincts that we actually have. The problem is we've now engineered the world to be so frictionless and so easy that the same energy saving instinct is starting to work against us. And we often try to push through this energy efficiency with sheer willpower.
09:34But honestly, this usually breaks down quite easily, and it's the reason why 80% of New Year's resolutions actually die off by February. And the gym is kind of half empty by March. So this isn't a personal failing.
09:45It's actually a strategy problem. Here's an example. We can try to change our lives on, let's say, three different levels.
09:50We can try to change the outcome. So we tell ourselves, I want to lose 10 pounds. We can try to change our processes.
09:55For example, I'm going to run four times a week, or we can change our identity, which would go something like, I am someone who runs regularly. It's so easy, and I used to do this as well, to start at either outcome or process based change. But that's why it doesn't really last because the identity underneath it all never shifted.
10:11And what I found worked was to stop asking, what should I do? And instead ask, who am I becoming? From this place, all of the other outcomes and behaviors flow naturally.
10:20And so here's an identity shift to counteract friction and starvation, which I really like. I am someone built for friction and doing hard things. Here's one potential action point.
10:28Look at the next twelve hours of your day and pick one moment where you can actually choose between things being easier or harder. For example, for me, every single day, I'm faced with the choice between taking the stairs or taking the escalator. And in Michael Easter's book, The Comfort Crisis, he talks about only 2% of people would actually take the stairs rather than taking the easier option of the escalator.
10:48And once we have that identity of being someone who chooses and embraces challenge, the actual behaviors and practices stop feeling like things we need to discipline ourselves into. They start to feel like just natural expressions of who you actually are. And so let's get into the four types of friction that are actually really worthwhile to add back into your life.
11:04Now, is the part of the video where the theory stops and the exciting action points begin. Before we dive in, I want to reiterate that not all friction in life is equal. Some friction is worth keeping, like the kind that makes you sharper, more resilient, healthier, but the other type, it's just tax, honestly, like with email admin.
11:20Now not many people know this, but when I'm not creating content, I'm in CEO mode running the company that my husband and I started called Sparkle Studios, which is the umbrella for our courses like the Lifestyle Business Academy, our personal brands, and also our software ventures. Ventures. All of that funnels through one inbox for me, which has turned into a daily mountain of mostly menial admin.
11:37And climbing this mountain every morning really isn't where my time should be going, which is why I want to tell you about Superhuman who are very kindly sponsoring this video. Their email tool, Superhuman Male, is part of the Superhuman productivity suite, and the whole system's been built with long term productivity in mind.
11:51Superhuman Male's AI handles the mundane admin so that I can stay focused on actual needle moving work that needs my human judgment. There are two especially high leverage features. The first is ask AI.
12:02Half of the time that I open a thread, I'm not actually replying. Instead, I'm actually just hunting for the tiniest details that someone's already sent before. With ask AI, I just type a question and the answer comes back in seconds.
12:13So now I don't have to troll through super long email threads anymore. The second feature is auto drafts. Auto drafts essentially helps me get unstuck on emails, which gives my brain the breathing room it needs to work through the hard stuff for my content and the business.
12:25So this might be a sign to stop chasing the next quick AI hack for emails and start actually using a system that makes email feel less overwhelming. You can sign up and get one month free of superhuman mail with my link description down below. Now let's get back into the video.
12:37We'll be strategically engineering positive friction into our lives in four key areas, physical, sensory, cognitive, and social. And the point isn't to do all of these at once and have it to completely revamp everything you're doing. It's actually just to simply find one or two ideas from each of these categories that you can maybe experiment with over the next few weeks.
12:52The first category is physical friction. This means things like movement, exercise, effort, temperature, hunger, manual work, all of the demands that our bodies evolved to actually expect. And as we learned about in the theory section, the body gets stronger by being asked to handle small repeated doses of discomfort, aka hormesis.
13:10Here are some specific practices that you could experiment with. The first one is something that I've been doing myself, which is taking the stairs instead of taking the lift or the escalator. This is a simple choice that might be presented to you maybe on your commute or whenever you're going out somewhere, but every single time that you make this choice, it actually does compound.
13:25Another similar switch is to walk instead of taking a car or taxi for anything that's under a kilometer. Then in terms of temperature, we have one of my absolute favorites, which is sauna. I go almost every day, and actually regular sauna use has been shown in studies to actually boost your cardiovascular health and trigger the release of something called heat shock proteins in your body, which actually really protective and have a lot of health benefits.
13:44On the other end of the spectrum is cold exposure. So maybe end your shower with thirty seconds of cold. This also includes ice baths or stepping outside in winter without a coat for a few minutes.
13:52Another option is fasting, also sometimes called time restricted feeding. During COVID lockdowns, I actually got very much into intermittent fasting, and I found it actually really boosted my energy and my mental clarity. And the next thing is to lift something heavy a few times a week.
14:05It doesn't actually have to be in a gym. I mean, you could do that if you want. It could also be body weight, kettlebells, household objects, even just carrying your groceries up the stairs rather than chucking them in the lift.
14:14The second category is about adding sensory friction. So this is all about adding in boredom, silence, slowness, spaciousness, which are these spacious sensory experiences that often modern life can root around with constant simulation.
14:26This matters because our brain needs this unstimulated time to consolidate, integrate, and settle. And there's actually science behind this.
14:34The default mode network is a specific brain network that only switches on when you're not focused on a task. So it activates during things like daydreaming, mind wandering, walking without listening to a podcast or music, or just staring out of the window. And you might notice that during these activities, find your mind just naturally wandering.
14:50This is exactly what the default mode network does. And the benefit of allowing it to run is it actually consolidates memories, processes emotions, and generates creative insight by connecting different parts of your life and thoughts that are going on.
15:02And so when you're doing nothing, your brain isn't actually doing nothing. It's doing some of its most important work. And the problem that the modern world presents is that there is constant input.
15:11There is scrolling, social media, podcasts, music, notifications, back to back content. This means that our default mode network barely gets the chance to switch on and run because we're stuck in passive consumption mode all day. So here are some specific practices to give your default mode network the space it needs to really breathe.
15:28The first one is to simply sit still for five minutes without your phone. You could call this a meditation. It's deliberately understimulating.
15:34And just notice the urge to reach for your phone, but then just come back to the present moment and let your mind do what it needs to do. Another idea is to eat at least one of your meals per day without a screen. So just the food, the chewing, the mindfulness of the conversation if you're with somebody.
15:47Another practice is to drive or walk without any podcasts or audiobooks or music or anything going on. Just let your mind wander in silence because this is where original thinking actually happens. Another practice is if you have a little bit of dead time in your day such as maybe going up in a lift or waiting in a queue or even going to the toilet, Try to not take your phone or not pull out your phone.
16:08Just stay present with whatever experience you're having. Here's another one that's made a big difference to me, which is not reaching for your phone for at least the first twenty to thirty minutes of the day. After you've just woken up, your brain is in what's called data state, and your nervous system is slowly coming online.
16:22And so if you immediately flood your brain with all of this hyper stimulating content on your phone, that's like a very abrupt start to your day. And actually, when you're in between sleep and wake, your brain is very open to suggestion and taking on new ideas and inspiration. As you want to protect that time for actually you starting up your day in an intentional and balanced way.
16:42And finally, maybe try one screen free evening a week. So no TV, no phone, no second screen. Instead, try activities like reading, talking, cooking, going to bed early, giving yourself that spacious mindful time.
16:54The third category is cognitive friction, and this is about deliberately challenging your brain. And this matters because neuroplasticity works in both directions.
17:02You either use your brain or you kind of lose it. And especially with AI coming onto the scene, it's getting easier and easier to remove cognitive friction from our lives. So here are some specific practices with AI related ones first because this is the current new battle.
17:15The first practice is to write and do your own thinking first and only then refine with AI. One way that I like to do this is with an app that actually we built out called VoicePal, which you install on your phone in the App Store and you hit record and just start speaking out any thoughts you're having to get to a first draft.
17:31And only then can you bring in AI to either ask follow-up questions or sharpen and edit what you've written. The next practice is to actually read the source and not just the AI summary. Because I found that summaries are okay for orientation, but for decisions and creation, the raw original material is actually so much more powerful.
17:47You can even try this out for yourself. If you ask AI to summarize a book that you recently read, you'll just notice that the AI summary, yes, it hits all the main points, but the way that the author wrote it in the original context actually hits different. The next practice is before you ask AI a question, maybe have a think or write down what you think the answer is or what you think the AI would say, and only then actually compare the two.
18:07The simple act of actively trying engages your brain and works those synapses. The next one is something that I've personally been battling with, which is doing mental math in my own head instead of immediately using a phone calculator. I've realized that at school, was amazing at mental math.
18:22I was so quick. I was just like that that that. But now simple addition, multiplication is starting to slow down, and I actually notice it.
18:29And so then just doing the math in your head first before double checking it with the calculator if you're really not sure about your own abilities. Another practice is to plan a route in your head before you actually open Google Maps to map it out. This is particularly relevant if you're actually already familiar with the place.
18:44So visualize the route that you're taking, and then check on maps if you want. Another one for things that you actually want to really retain or engage with emotionally is to actually handwrite things. Studies have found that by handwriting notes, you actually engage with them much more deeply, and it activates a lot more of the brain.
19:00And the final thing is something that's becoming rarer and rarer, which is training the muscle of sustained attention by staying with one cognitive task for at least thirty minutes. No task switching, no multitasking, one single tab, one single track of focus.
19:14And as a more general principle, here are some questions I like to ask to see if I'm really critically engaging with AI. The first one is, what's the actual question? The second one is, what is the goal of the output?
19:24And thirdly is, what would I say if I had to do this from scratch without AI helping? And the fourth category is social friction. And this means choosing the harder, more intense version of any human interaction.
19:35There's a phrase I heard online somewhere that I keep coming back to, which is that everyone wants a village, but no one wants to be a villager. And when I heard this, I felt maybe a little bit called out. But the reality is you don't passively inherit community as an adult.
19:47You have to actively build it. Instead of just going to school or uni and showing up to your community and passively inheriting that community. You have to choose to host people, make plans, sustain the group chat, be the chief of your own village.
19:58And this is something I realized recently that it's way harder to make friends as an adult than at school or uni because you don't have a default group of people that you're always hanging out And so then that means it just takes real effort and investment of energy. And the problem with always just defaulting to the comfortable option without putting in that much effort or energy is that then you end up kind of lonely and isolated.
20:17And so here are some things I've been trying to do instead. Firstly, it's a call instead of text. This is especially for anything that truly matters.
20:24Another thing is to just show up and say yes. And, yes, this takes effort. And, yes, it sometimes doesn't always feel like it's something we can do, but as much as possible encouraging ourselves to be that kind of person who shows up.
20:34The next one is to say the hard thing, the scary thing, the thing that makes you think, oh gosh, like, this feels important and I want to say it, but I'm a little bit scared. Because I've noticed these days as connection becomes more and more online, I wonder if we've forgotten how to be bold and just say the thing that is kind of on our mind and and that needs to be said.
20:53The next one is to initiate. Become the chief of the village. And don't just say we should hang out.
20:58Actually, send the invite. Actually, pick a date. Actually, execute on it and make it happen.
21:02And the final one is to choose to make at least one new real friend this year, like a deep real friendship. Because it's easier than ever to have multiple relatively lightweight friendships, but actually going deep with one person and really connecting with them is what we often lose in adulthood as we leave those areas of our life where we automatically hang out with people all the time.
21:22And at the end of the day, the framework in this video gives you the map, but the map isn't actually the journey or the work itself. The journey itself lies in the identity that you decide to take on and all the small votes that you cast every single day for who you're becoming. So just like at the end of every video, I'd like to invite you to choose two action points that you're taking away from this video and that you're going to implement starting today.
21:40So pick two and write them down somewhere in your journal, your notes app, the comments below, and email to a friend. And I've had some requests in the comments to suggest two great action points. And, obviously, pick any that you want, but here are two.
21:50The first one is to cast one identity vote. Find one moment in the next twelve hours where you have to choose between easier and harder and pre commit to the harder one. And the second one is to run one micro experiment.
22:00Pick one of the four categories we walked through and try a single practice from it for the next seven days. The friction audit in the description will help if you're not sure where to start. If you like this video, I think you'll like this video over here, which is my video on digital anhedonia, which is the sister concept to friction starvation.
22:14And the two of them together give you a fuller picture of what modern life is doing to us and our brains and what to do about it to live well in the modern era. As always, thank you so much for watching. Take care of yourself, and remember that the journey is the destination.

The Hook

The bait, then the rug-pull.

Hunter-gatherers walked 16,000 steps a day. The modern adult walks four times fewer and increasingly outsources thinking to AI. That gap between the friction-rich lives humans evolved for and the frictionless convenience we have built is the premise of a 22-minute argument: restlessness, purposelessness, and burnout are not character flaws. They are a biological mismatch signal.
