How to Get Your Brain Addicted to Hard Things, Not Cheap Dopamine
A neuroscience-behavior-psychology breakdown of why modern dopamine culture makes discipline feel impossible, with one concrete fix per problem.
August 18thThe argument in one line.
Overthinking isn't a sign of intelligence, it's the brain's strategy for avoiding the uncertainty of taking action, and it only stops once you write down a plan and start acting instead of analyzing.
Read if. Skip if.
READ IF YOU ARE…
- You keep researching, planning, or analyzing an idea for months without ever actually starting it.
- You've told yourself you overthink because you're 'just too smart' or 'too analytical' and want to know if that's really true.
- You have a running list of half-finished decisions, unanswered messages, or unstarted projects that keep resurfacing in your head.
- You want concrete, testable exit points instead of generic 'just stop overthinking' advice.
SKIP IF…
- Your overthinking affects your sleep, relationships, or health on a daily basis, that's a clinical concern this video explicitly says it can't fix.
- You're looking for a productivity or time-management system. This is about the emotional mechanism behind stalling, not calendars or to-do apps.
The full version, fast.
The video's core claim: overthinking isn't intelligence at work, it's the brain avoiding uncertainty. Any decision with an unknown outcome triggers a 'certainty loop': you overanalyze for temporary relief, but real certainty never comes because it can only be reached by acting and living the outcome. Unfinished decisions also linger as 'open tabs' in your mind (the Zeigarnik effect), and research shows writing down a concrete next step, not finishing the task, is what actually closes them. Three practical exits follow: write down every open loop with its next step, shrink the action into something small enough to attempt, and act to gather evidence instead of analyzing further. It closes by naming four overthinker types: the Replayer, the Catastrophizer, the Overplanner, and the Overanalyzer.

01 · Cold open + the 'you're just smart' misconception
Opens on the struggle of overthinking, establishes the host's credentials (Penn, computation and cognitive science), then names the common misconception that overthinking is just a byproduct of being analytical or smart.
00:58 – 02:38
02 · The YouTube channel that never launched
Personal example: wanting to start a YouTube channel but spending months and years overthinking gear, editing software, and content ideas instead of actually starting, used to ask why overthinking doesn't help.
02:38 – 03:40
03 · The Certainty Loop
Introduces the certainty loop: taking action means facing uncertainty, the brain treats that as a threat and offers a 'deal' to research more instead of acting; cites Thomas Borkovec's research framing overthinking as emotional avoidance.
03:40 – 05:09
04 · The Zeigarnik Effect — open tabs
Every unmade decision or unsent message stays open in the mind like a browser tab until resolved; Baumeister and Masicampo's research shows writing a concrete plan, not finishing the task, is what stops the intrusive thoughts.
05:09 – 07:18
05 · Fix #1 — empty the tabs (+ Paperlike sponsor read)
First fix: write down every open loop and a concrete next step for each. Segues into a sponsored segment for the Paperlike 3 iPad screen protector she uses for this brain-dump process.
07:18 – 07:56
06 · Fix #2 — shrink the action
The bigger an action feels, the more uncertainty it carries, so cutting it into small, achievable chunks lowers the uncertainty enough to actually start.
07:56 – 09:01
07 · Fix #3 — act for evidence
You can never analyze your way into certainty, only acting and seeing the result resolves it; ties in the idea that procrastination is an emotion regulation problem, not a time management one.

Lines worth screenshotting.
- Overthinking isn't caused by being unusually smart or analytical, it's the brain avoiding the uncertainty that comes with taking action.
- Taking action means facing an unknown outcome, and the brain treats that uncertainty as a real threat, so it offers a 'deal': research more instead of acting.
- The certainty loop runs in four steps: a decision with an uncertain outcome, uncertainty that feels threatening, overthinking for temporary relief, and uncertainty returning because it was never actually resolved.
- Certainty about an outcome can only come from living it, so no amount of extra research or analysis before acting will ever produce it.
- Researcher Thomas Borkovec's decades of work at Penn State found that overthinking functions as emotional avoidance, letting you engage with a problem at arm's length instead of feeling the uncertainty directly.
- The Zeigarnik effect means every unmade decision or unsent message stays open in your mind like a browser tab, resurfacing at random moments until it's resolved.
- Researchers Baumeister and Masicampo found that writing a concrete plan for an unfinished goal, not completing the goal itself, is enough to stop the intrusive thoughts about it.
- The first fix is writing down every open loop in your mind with a specific next step for each one, turning a vague thought into an actionable plan.
- The second fix is shrinking the action: the bigger a task feels, the more uncertainty it carries, so cutting it into small achievable chunks lowers the uncertainty enough to start.
- The third fix is acting for evidence, since you can never analyze your way into knowing whether a plan will work, only doing it will tell you.
- Procrastination is framed as an emotion regulation problem, not a time management problem, driven by a wish to avoid the negative feelings tied to potential failure.
- Four overthinker types are named: the Replayer (re-runs past conversations), the Catastrophizer (pre-lives worst-case outcomes), the Overplanner (turns preparation into its own project), and the Overanalyzer (mistakes analysis for productive work).
Overthinking is avoidance, not intelligence
PSYCHOLOGY OF STALLING
Every certainty loop trades taking action for temporary relief through analysis, but real certainty only ever comes from actually doing the thing and living the outcome.
02The YouTube channel that never launched
- Wanting to start something and spending months or years researching gear, software, or topics instead of starting it is itself overthinking, not preparation.
03The Certainty Loop
- Every decision with an uncertain outcome triggers the same four-step certainty loop: uncertainty feels threatening, you overthink for temporary relief, and the uncertainty returns because it was never actually resolved, since real certainty only comes from living the outcome.
- Overthinking functions as emotional avoidance, letting you engage with a problem at a safe distance instead of feeling the uncertainty or discomfort head-on.
04The Zeigarnik Effect — open tabs
- Every unmade decision, unfinished task, or unsent message stays mentally 'open' like a browser tab and keeps resurfacing at random moments until it's resolved.
- Writing a concrete plan for an unfinished goal, not completing the goal itself, is enough to stop the intrusive thoughts tied to it, according to Baumeister and Masicampo's research.
05Fix #1 — empty the tabs
- Write down every open loop in your mind, from major decisions to a forgotten reply, and give each one a specific next step to turn it from a thought into a plan.
06Fix #2 — shrink the action
- The bigger an action feels, the more uncertainty it carries, so cutting it into small, achievable chunks lowers the uncertainty enough to actually start.
07Fix #3 — act for evidence
- You can never analyze your way into knowing whether a plan will succeed, only doing it and seeing the result actually resolves the uncertainty.
- Procrastination is an emotion regulation problem, not a time management problem, driven by a wish to avoid the negative feelings tied to potential failure.
08The Four Overthinker Types
- The Replayer keeps re-running past conversations for mistakes that can no longer be changed.
- The Catastrophizer pre-lives worst-case outcomes before starting, so a bad result won't come as a surprise.
- The Overplanner turns preparation into its own project, stacking backup plans on backup plans instead of doing the original task.
- The Overanalyzer mistakes the busywork of notes, spreadsheets, and research for actual productive progress, which makes it the hardest type to self-recognize.
09Everyday overthinking vs. something more serious
- Occasional overthinking that slows down a decision is different from overthinking that disrupts sleep, relationships, or health daily, the latter is worth addressing with a professional, not a video.
Terms worth knowing.
- Certainty Loop
- A repeating cycle where an uncertain decision triggers overthinking for temporary relief, but real certainty never arrives because it can only come from actually acting and seeing the outcome.
- Zeigarnik Effect
- A psychological phenomenon where the brain keeps unfinished tasks, decisions, or messages mentally 'open' and resurfaces them unprompted until they're resolved.
- Emotional avoidance
- Engaging with a problem only through research and analysis, at a safe emotional distance, instead of directly feeling the uncertainty or discomfort it carries.

metaphor
If you struggle with taking action because you overthink absolutely everything and you watch other people easily work on their plans without agonizing over every single step, believe me, there is nothing wrong with you. There's a cycle of overthinking happening in your brain that is actually trying to protect you.
And in this video, we're gonna learn how to work around it so we can finally pursue our goals with ease. My name is Olga. I just graduated from the University of Pennsylvania where I studied computation and cognitive science.
And after the last four years of studying how the human mind works, this is genuinely one of the most interesting things I've learned about. There's a common misconception that you overthink because you're just very analytical. Your brain works just harder than other people's.
You think too much. You're just way too smart. And obviously, this framing feels kind of good because it turns a problem that people have into kind of like a compliment.
But imagine a situation. Let's take an example from my life. I, for the longest time, wanted to become a YouTuber and start a YouTube channel.
But instead of actually creating a YouTube channel, I spent months and years thinking about what gear I have to get, what sort of editing software to use, what would I even make videos about.
So I was just thinking and thinking and thinking about it, and overthinking every single step that I have to take to actually start a YouTube channel. So explain to me how exactly does overthinking help us here. Because I cannot see why overthinking, over worrying, over researching can be helpful because it basically delays the moment when you actually have to take action and see the result.
So if overthinking is not helping, why does our brain keep doing it instead of just taking action? Well, because taking action means that you have to face uncertainty, and our brains hate uncertainty.
When you're recording the first video, you don't know if it's gonna be good. You don't know if people are gonna judge you. You don't know if the idea you've been planning is going to survive contact with reality, and our brain hates that uncertainty.
Our brain basically treats that uncertainty as a real threat. Instead of letting you take action and find out what is going to happen, which would actually resolve that uncertainty, .
Your brain says, oh, do not do this scary thing yet. Do not do this. Research a little bit more, think about it a little bit more, analyze it a little bit more.
Oh, and then we're going to have certainty. Then we're gonna know what is the best course of action. And your mind creates something that I personally like to call like a certainty loop.
So first, you're faced with a decision or a goal or a plan that has an uncertain outcome. And that uncertainty, it feels very threatening.
So in order to resolve the uncertainty, you start to overthink. You start to overanalyze, compare options, do planning, and that gives you temporary relief from the uncertainty.
But the certainty never actually arrives because you cannot be certain about an outcome before you've actually lived it. So the uncertainty comes back, and it only will be resolved once you're actually done with the action, done with the plan.
A researcher named Thomas Borkovitz at Penn State University studied this problem for decades, and he actually found out that overthinking functions as emotional avoidance.
When you research and you analyze and worry, you're actually engaging with the problem at arm's length, and that protects you from the actual feeling of uncertainty. And there's another reason why this overthinking loop is so hard to escape.
So there's a phenomenon in psychology called the Zeigarnik effect, and it's when your brain treats every unfinished task, every unmade decision, every unsent message is basically an open tab.
So if you were to imagine and you're clicking through different things, you're thinking about many different, uh, ideas, every single unmade decision would stay as an open tab in your brain, and you would always see it on the on the top of the browser. For example, you know when you receive an important email, but you do not immediately reply to it.
And then, in the middle of the day, you're going to keep remembering about replying to this email. In the middle of a conversation with someone, in the shower, taking a walk, you're always going to be getting reminded by your brain that, oh, there's an email I have to reply to, there's an email I have to reply to. And it's never going to actually leave you until you go and reply to that email.
And it keeps running in the background because it is your brain's way of making sure that important things do not get forgotten. So when you're stuck in the certainty loop, you never actually act on anything.
You keep overthinking and trying to reach that certainty, but the certainty never arrives because you never actually complete the action. And that's where the Zeigarnik effect comes in because you keep being reminded by your brain about all the plans that you have, and it's actually just it's like a ton of open tabs in your mind that keep cluttering your mental space.
So how do we actually ? You might think that you have to make every decision, finish every task, complete every project, but no.
Researchers Baumeister and Mazze Campo found something very interesting. They found that your brain doesn't actually need every task to be done.
It just needs to create a plan to resolve it. When people in their study took an unfinished goal and they wrote down a specific plan of how they would complete it, their intrusive thoughts, their overthinking, it stopped.
So the first exit from the certainty loop is very simple. So you sit down, you take pen and paper, and you write down every single open tab that you have in your mind. So every unmade decision, every plan, every dream you have, everything that you keep thinking about.
Also, minor things as well. Every random email that you forgot to reply to, every message you forgot to reply to, and just write it down from your mind and onto paper. Then for each one of them, write a concrete next step of how you're going to resolve it and how you're going to turn a thought into an action.
Personally, I love to write a brain dump like this on my I Pad. It's where I write my notes, my plans, my tasks I have to do, plan my videos. I use a screen protector called Paperlike three, which has this nano dot surface and it gives you real friction when you write.
So it basically feels like you're writing pen on paper instead of writing pen on glass. And they spend years testing and producing this NanoDots technology that has this paper feel experience without actually compromising the clarity of your screen. I also have to mention installation because I definitely ruined screen protectors before, but Paperlike three has this butterfly application system.
It basically makes it impossible to mess up. It keeps your screen sealed from dust until the exact moment the protector goes on, and there's also an interactive guide on your iPad that walks you through everything step by step. So I got it perfect on the first try.
If you wanna try it, I'll put my link in the description, and they also have a one hundred day money back guarantee. So there's genuinely no risk.
And it comes in a pack of two, so you always have a spare. And thank you to Paperlike for sponsoring this video. Fix number two, shrink the action until your brain can't resist it.
Remember, the loop spins because the action feels way too big. Starting a YouTube channel, launching a whole business, having a whole difficult conversation. Basically, the bigger the action, the more uncertainty it carries.
So if you're going to shrink the action, make it very small, and cut it down into very small achievable chunks, you're going to feel less uncertainty when you try to complete that like one small step. Fix number three, act for evidence.
The certainty loop makes you a promise. It says that if you think about it a little bit more, you're finally going to achieve certainty. But it doesn't work this way.
You will never analyze your way into knowing whether your business idea is going to succeed. You have to go and you actually have to do it and then you're going to find out. So you're never going to know whether your goal or your plan is going to be successful.
You have to go and actually turn it into the physical reality. I also love this related idea from procrastination research and it says that procrastination is not a time management problem.
It is an emotion regulation problem, and I talked about it extensively in this video. I'm gonna link it somewhere here. But it's very interesting because we productively procrastinate on our goals and on our dreams because we just want to avoid the negative emotions of thinking about potential failure and the uncertainty of the outcome that we're going to reach.
Now, I have given you all the fixes that have helped me with dealing with overthinking that I've learned through my personal experience with talking to people, reading books and articles, and these fixes probably are going to help if you actually know that you're overthinking. But some people overthink without actually realizing that they are overthinking.
So I think it's very helpful to know about different types of overthinking and how it can show up in our lives. So now I'm going to give you four overthinking types, and let me know in the comments if you recognize any of them in yourself, and maybe you don't recognize some of them in yourself. Be very curious to hear.
Number one is the replayer. Imagine you had a conversation with someone three days ago, and you're still thinking about it. You're still playing it over in your head and thinking, oh, I should have said this.
Maybe maybe I said something wrong. Maybe I said something insensitive.
Maybe maybe I should say something else next time. And you keep overthinking it despite the fact that it already happened, and the conversation has already taken place. So you cannot actually change anything you said in that conversation.
Of course, a lot of us do it in like our daily lives, especially if we accidentally say something that we did not mean to say. But if you find yourself doing it constantly with, a lot of conversations, you're definitely the replayer.
Number two is the catastrophizer, It's when you have a certain goal or a certain plan, and before you even started pursuing it, you already imagined 20 different ways that is going to go wrong. So you're constantly pre living different disasters and worst case scenarios, so that if they do happen, you're not going to be surprised by them, and you're not going to be too disappointed.
Number three is the over planner. It's when your plan has an other plan, when your backup plan has another backup plan, you've been getting ready to do something for so long that the preparation itself becomes an entire new project even of itself. So you're basically wasting time on preparation instead of doing the actual original project.
Number four is the over analyzer, and this one is me, and it's basically when you want to analyze every single course of action. It feels like the most dangerous form of overthinking because you generally feel productive when you overanalyze, when you take notes, when you create spreadsheets, when you do research to prove that you are actually working.
Let me know in the comments which one of these characters is you. I'd be very curious to hear from you and how you actually deal with these forms of overthinking. And also, if you know any other forms of overthinking that I didn't mention in this video, I'd also be very curious to hear and to learn something new.
So we have now discussed why we overthink our actions and how we can stop doing that, but I also want to add one very, very important thing. Everything I discussed today is about everyday overthinking. It's the type of overthinking that can slow you down a little bit, can make it a little bit slower to take action, or it may be a little bit harder for you to make a decision because you keep thinking about it.
But if overthinking is consuming most of your days, if it's affecting your sleep, your relationships, your health, this is not something a YouTube video can fix.
This is definitely something that is worth talking to a professional about. But if this is daily overthinking, I'm always happy to share my experience and what I think about it.
Also guys, I have not been posting for a while, and thank you so much for checking in on me, because some of you have reached out and asked if I'm okay. But I am okay. So the thing that happened is that I graduated from college, I moved from Philadelphia to San Francisco, and this entire time I was trying to find an apartment in San Francisco.
If you know anything about San Francisco, you know that the apartment search here is absolutely insane right now. I spent such a long time trying to find an apartment, and I'm so happy that I'm finally I moved and I settled into my cozy little studio here.
So from now on, I will be recording my videos in here. And if you learned something new in this video, I'd really appreciate if you like this video and subscribe to my channel. And right now, I'm trying to build out this big library of videos about cognitive science, psychology, neuroscience, maybe some other topics as well.
And if you have any sort of topics or themes that you would be interested to hear my perspective on and to do a little bit of research on, do let me know in the comments, and I'd be very happy to hear your ideas. And thank you so much for watching.
