Neuroplasticity: Rewiring Your Brain To Do Hard Things
Why your brain fights change and how to win the battle through neuroplasticity
“new year, new me.”
how many times have you heard that phrase? hell, some of you are probably guilty of saying it yourselves.
i know i am.
january 1st, the day millions of people wake up with this weird optimistic delusion that somehow the calendar flipping over magically transformed them into a different person.
“this year i’m gonna hit the gym.”
“this year i’m gonna start that business.”
“this year i’m gonna quit my shitty habits and become the person i always wanted to be.”
and then february hits. maybe march if they’re really disciplined.
and they’re right back where they started. same person, same patterns, same life.
the gym membership goes unused. the business idea stays an idea. the habits come crawling back.
why?
because they fundamentally misunderstand how change actually works.
they think change is about motivation or about willpower. they think just “wanting it bad enough” will work
it’s not. it never will.
change is about neuroplasticity. it’s about literally rewiring the physical structure of your brain so that the new behavior becomes as automatic as the old one.
and nobody talks about this. nobody explains the actual mechanism.
so people keep failing, keep blaming themselves for “not having enough discipline,” and keep repeating the same cycle every january.
fuck that.
it’s 6:47am right now. i’m sitting at my desk with a cup of black coffee sweetened with raw honey because refined sugar is for people who hate their brain cells.
dark ambient music playing through my speakers. some artist i can’t even pronounce the name of, just sounds like the inside of a cathedral at 3am.
rain hitting my window. not that romantic movie rain. sounds more like that constant ticking of a clock.
my whiteboard next to me is covered in marker scribbles from last night. diagrams of neural pathways, notes on hebbian learning, arrows pointing everywhere like i’m planning a heist.
i’ve been thinking a lot about neuroplasticity lately. about how your brain is basically just meat that learned to think, and how that meat can be reshaped if you understand the mechanics.
and i want to download everything i’ve learned into your brain right now because this shit is genuinely life-changing if you actually understand it.
this isn’t a step-by-step guide. i’m not gonna give you “5 easy tricks to rewire your brain.” if thats’s what your looking for then your in the wrong place.
this is a deep dive into what’s actually happening in your skull when you try to change, why most people fail, and what you need to know to not be one of them.
let’s get into it.
WHAT NEUROPLASTICITY ACTUALLY IS
"Your brain is not fixed. Your brain is not hardwired. Your assumptions about how much you can grow and change are holding you back." - Carol Dweck
your brain is not fixed.
this seems obvious now, but for most of human history, scientists believed that once you hit adulthood, your brain was basically done developing.
you got the neural structure you got, and that was it for life.
turns out that’s complete bullshit.
your brain is constantly rewiring itself based on what you do, what you think, and what you pay attention to.
every single experience you have, every thought you think, every action you take is literally reshaping the physical structure of your brain.
this is neuroplasticity. the brain’s ability to form new neural connections and reorganize existing ones.
neuroplasticity is value-neutral.
it doesn’t care if you’re building good habits or bad ones. it doesn’t distinguish between productive patterns and destructive ones.
your brain just reinforces whatever you do repeatedly.
if you scroll tiktok for three hours every night, your brain optimizes for that. builds stronger pathways for distraction and dopamine-seeking.
if you read for three hours every night, your brain optimizes for that. builds stronger pathways for focus and information processing.
the mechanism is the same. the brain doesn’t judge. it just adapts.
and this is why “new year new me” fails so spectacularly for most people.
they’re trying to overlay new behavior on top of old neural architecture without understanding that the old pathways are still stronger.
it’s like trying to redirect a river. you can dig a new channel, but if the old channel is deeper and more established, the water’s gonna keep flowing that way.
THE NEUROSCIENCE OF WHY CHANGE IS HARD
your current habits, behaviors, and patterns exist because they’re neurologically efficient.
your brain has spent years, maybe decades, myelinating those neural pathways.
myelin is this fatty substance that wraps around neural connections and makes signals travel faster. the more you use a pathway, the more myelinated it becomes, the more automatic the behavior.
this is why your bad habits feel effortless. they’re running on superhighways of myelin.
when you try to build a new habit, you’re creating a brand new neural pathway from scratch. no myelin, slow signal transmission, requires conscious effort every single time.
and your brain fucking hates this.
your brain is an efficiency machine. it’s constantly trying to automate as much as possible to save energy.
conscious effort requires a ton of glucose and oxygen. it’s metabolically expensive.
so your brain is literally fighting you every time you try to do something new because from its perspective, you’re wasting precious resources on an unproven pathway when there’s a perfectly good myelinated highway right there.
this is the internal resistance you feel when you try to change.
it’s not weakness, never associate it with weakness, it’s not lack of discipline either.
it’s simply your brain doing exactly what it evolved to do and trying to conserve energy by defaulting to established patterns.
now here’s where it gets a little tricky.
your brain also predicts the future based on the past.
there’s this thing called predictive processing where your brain is constantly generating predictions about what’s going to happen next based on what usually happens.
if you usually eat like shit, your brain predicts that you’re going to eat like shit today. and then it generates the cravings and impulses to make that prediction come true.
if you usually procrastinate, your brain predicts that you’re going to procrastinate today. and then it makes you feel resistant to starting work.
your brain is essentially running a self-fulfilling prophecy loop based on your past behavior.
breaking out of this requires understanding that you’re not just fighting habits. you’re fighting your brain’s entire predictive model of who you are.
IDENTITY IS NEUROLOGICAL
"You cannot change your destination overnight, but you can change your direction overnight." - Jim Rohn
this is the part most people miss entirely.
when you say “i am” something, you’re not just describing yourself. you’re reinforcing a neural pattern.
“i’m not a morning person” isn’t just a statement. it’s a neural pathway that your brain uses to predict and generate behavior.
every time you say it, think it, or act on it, you’re strengthening that pathway.
your identity is literally encoded in the structure of your brain as a collection of self-referential neural patterns.
and your brain treats your identity as ground truth. it’s the foundation of its predictive model.
so when you try to do something that contradicts your identity, your brain throws up massive resistance because you’re threatening the integrity of its predictive model.
if your identity is “i’m not a gym person,” and you try to start going to the gym, your brain is going to fight you every single day.
not because you can’t physically do it. because it contradicts the neural pattern of who your brain thinks you are.
this is why identity-level change is so much more powerful than behavior-level change.
i’ve wrote about behavior level change in the past but i haven’t gone to deep into identity-level change.
think of it like this.
if you’re trying to change a behavior while keeping the same identity, you’re pushing a boulder uphill forever.
your like sisyphus.
but if you change the identity first, the behavior flows naturally from it.
the person who identifies as “someone who takes care of their body” doesn’t need willpower to go to the gym. it’s just what they do. it’s consistent with their neural model of self.
the person who identifies as “a learner” doesn’t need to force themselves to read. it’s automatic. it’s who they are.
when you wake up you brush your teeth automatically, it doesn’t require mental effort and you don’t feel resistance because you identify as “someone who has clean teeth and good breath”
but here’s the thing, you can’t just decide to have a new identity and expect your brain to accept it.
your brain doesn’t believe statements. it believes evidence.
if you tell yourself “i’m a disciplined person” while your behavior shows zero discipline, your brain dismisses the statement as noise.
it trusts behavior over belief.
so the only way to change identity is through behavioral evidence that accumulates over time until your brain updates its model.
you prove the new identity to yourself through repeated action until the new neural pattern is stronger than the old one.
this is why the first few weeks of any change are absolutely brutal. you’re in this awkward phase where your behavior is saying one thing but your identity pattern is still saying another.
your brain is basically in conflict with itself. old pattern vs new pattern. and the old pattern is way more myelinated.
most people quit during this phase because the cognitive dissonance is uncomfortable as fuck.
but if you can push through it, there’s a tipping point where the new pattern starts to become self-reinforcing.
you’ve built enough myelin on the new pathway that it starts to compete with the old one. your predictive model starts to shift.
and that’s when change stops feeling like forcing yourself and starts feeling like just being yourself.
THE ROLE OF STRESS AND DISCOMFORT
here’s something that’s gonna sound contradictory, you need stress to rewire your brain.
neuroplasticity doesn’t happen in comfort it happens under challenge.
when you’re doing something easy and familiar, your brain is in default mode. just running established programs.
but when you’re doing something difficult, something that requires real effort, your brain releases neuromodulators like norepinephrine and acetylcholine.
these chemicals create a state of heightened alertness and focused attention. they mark whatever’s happening right now as “important, pay attention, encode this.”
this is the neurochemical signal that triggers plasticity.
without it, you’re not actually creating lasting change. you’re just going through the motions.
this is why people always say to step out of your comfort zone.
your comfort zone is neurologically stagnant.
when you’re comfortable, your brain isn’t releasing the chemicals needed for plasticity. you’re not encoding anything new.
you’re just reinforcing existing patterns.
growth requires putting yourself in situations where you’re legitimately challenged. where you’re operating at the edge of your current capabilities.
if you feel discomfort it’s not a sign you’re doing something wrong it’s simply the signal that neuroplasticity is happening.
your brain is being forced to adapt because the current neural configuration isn’t sufficient for the task.
this is why people who constantly seek comfort never really change. they’re avoiding the exact conditions necessary for rewiring.
and this is why the most effective way to change is through repeated exposure to challenging situations.
not traumatically challenging. not overwhelming. but challenging enough that your brain has to work.
athletes call this “training at the edge.” always pushing slightly beyond your current ability.
same principle applies to any kind of change. you need to be operating in that zone of productive discomfort.
if it’s too easy, no plasticity. if it’s too hard, you shut down. but right at the edge? that’s where your brain rewires fastest.
running is one of my favourite ways to go to the edge. when i start to feel tired and tell myself to quit that’s the most important moment because thats where i decide i have to keep going.
REPETITION AND TIME
"We are what we repeatedly do. Excellence, then, is not an act, but a habit." - Aristotle
now here comes the part nobody wants to hear. people think you can do this in a couple of days or even a month the truth is rewiring your brain takes time.
there’s this myth that it takes 21 days to form a habit. or 66 days. or whatever arbitrary number someone made up. i see it all the time on social media.
the reality is that it depends entirely on the complexity of the behavior and how different it is from your existing patterns.
simple behaviors in low-resistance contexts can become automatic relatively quickly. maybe a few weeks.
complex behaviors that contradict deep identity patterns can take months or even years to fully solidify.
the research on habit formation shows massive individual variation. some people can automate a behavior in 18 days. others need 254 days for the same behavior.
there’s no universal timeline. your brain rewires at the pace it rewires.
so when you hear someone on social media say ‘do this for x amount of days and it becomes a permanent habit’ and then you go ahead and do it but still feel resistance, just understand there is nuance.
the key mechanism is consistent though: repetition.
every time you perform the new behavior, you’re strengthening that neural pathway. you’re adding a little more myelin.
and every time you don’t perform it, you’re letting the old pathway maintain its dominance.
this is why consistency matters more than intensity.
doing something once with massive effort doesn’t create lasting change. you haven’t built enough myelin. the pathway is still weak.
but doing something small consistently over a long period of time builds that myelin up layer by layer until the pathway is strong enough to compete with and eventually replace the old one.
the people who successfully change aren’t the ones who have massive bursts of motivation. they’re the ones who show up consistently even when motivation is zero.
i’m sure a lot of you have plans for the gym/fitness, lose weight, gain weight, whatever it is you want to do.
just show up everyday. that’s all the matters.
somedays your going to feel like absolute shit, your not going to train until failure, your going to have improper form, your going to be tired. just show up.
even if you go and do 1 set and leave the fact that you showed up is what matters.
people who are consistent understand that they don’t need to perform the behavior perfectly. they’re just trying to myelinate the pathway.
every repetition counts. even half-assed ones. because you’re still sending signals down that pathway and reinforcing the connection.
THE ATTENTION FACTOR
what you pay attention to literally shapes your brain.
there’s this concept in neuroscience called “neurons that fire together, wire together.”
when you focus your attention on something, you’re activating specific neural circuits. and when those circuits are active at the same time, they form stronger connections with each other.
this is how skills are built. how knowledge is integrated. how patterns are learned.
but it also means that where you direct your attention is determining what your brain optimizes for.
if you’re constantly paying attention to negative shit, your brain builds stronger pathways for negativity. you literally become neurologically predisposed to notice and focus on negative things. we usually label these people as ‘pessimists’
if you’re constantly paying attention to what you don’t have, your brain reinforces scarcity thinking.
if you’re constantly paying attention to distractions, your brain optimizes for distraction and weakens your ability to sustain focus.
this is why doom-scrolling is so neurologically damaging. you’re training your brain to seek novelty and react to negative information. i could make a whole post on doomscrolling and how destructive it is. our phones in general
doomscrolling is literally rewiring yourself to be anxious and distractible.
but the reverse is also true.
if you deliberately direct your attention toward things you want to reinforce, you’re building those pathways.
if you want to be more grateful? practice actively noticing things you’re grateful for. your brain will start automatically scanning for things to be grateful about.
want to be more focused? practice sustaining attention on single tasks. your brain will build stronger circuits for sustained attention.
this is why mindfulness and meditation aren’t just woo-woo bullshit. they’re literal attention training.
you’re practicing the skill of directing and sustaining your attention, which strengthens the neural circuits that control attention.
and those circuits then transfer to everything else you do.
the ability to control your attention is the ability to control what your brain reinforces.
and that’s the closest thing to a superpower that exists neurologically.
ENVIRONMENT SHAPES BRAIN
"The mind is not a vessel to be filled, but a fire to be kindled." - Plutarch
your environment is constantly influencing your neural patterns.
“you are who you hang around” “show me you 5 closest friends i’ll show you your future”. all these phrases are talking about the same thing neurologically.
if you’re in an environment full of cues for your old behavior, your brain is going to keep defaulting to it because that’s what the environmental context predicts.
this is why people who try to quit smoking while still hanging out with smokers usually fail. the environmental cues are too strong.
your brain sees the social context, smells the smoke, and every single cue is activating the neural pathway for smoking.
trying to resist that with willpower alone is fighting against your entire environmental setup.
the smarter approach is to change the environment to support the new behavior.
remove cues for old patterns. add cues for new patterns.
if you want to read more, put books in visible places. remove your phone from the bedroom. create environmental friction for distraction and environmental ease for focus.
your brain is lazy (in a good way). it follows the path of least resistance.
so if you set up your environment so that the path of least resistance leads to the behavior you want, you’re working with your brain instead of against it.
this is also why your social environment matters neurologically.
humans have mirror neurons that fire both when you perform an action and when you observe someone else performing it.
this is the neural basis for learning by observation. but it also means you’re literally mirroring the behaviors and patterns of people you spend time with.
if everyone around you has shitty habits, your brain is constantly activating and reinforcing those same patterns just from observation.
if everyone around you is disciplined and growth-oriented, your brain is mirroring and reinforcing those patterns.
this isn’t about “positive vibes” or motivation. it’s about neural mirroring.
your brain is a social prediction machine. it’s constantly updating its model based on what behaviors are normal and expected in your social environment.
so if you want to change, one of the most powerful things you can do is change your environment to one where the behavior you want is normal.
THE TIMING PARADOX
here’s something weird about neuroplasticity.
it’s easy to think it happens in the moment you’re performing the behavior.
in reality, it happens during rest. specifically during sleep.
when you’re learning something new or practicing a new behavior, you’re creating temporary changes in neural activity.
but those changes don’t become permanent until your brain consolidates them during sleep.
this is why sleep is so fucking critical for any kind of change.
people who try to change while chronically sleep-deprived are fighting with one hand tied behind their back.
you can put in all the effort during the day, but if you’re not sleeping enough, your brain isn’t consolidating those changes into lasting neural restructuring.
you wake up the next day and it’s like you’re starting from scratch because the plasticity didn’t get locked in.
WHY MOST PEOPLE FAIL
let’s be real about why “new year new me” almost always fails.
it’s not because people are weak or lazy or lack discipline.
they set a goal: “i’m going to work out 5 times a week.”
and then they try to use willpower to force themselves to do it.
but they haven’t addressed:
the identity pattern that says “i’m not a gym person”
the environmental cues that make the old behavior easy and the new one hard
the lack of immediate neurological reward for the new behavior
the fact that the old pathway is way more myelinated
the reality that their brain’s predictive model is still based on their past behavior
so they’re essentially trying to swim upstream against their entire neural architecture.
and it works for a few weeks. maybe a month if they’re really determined.
but eventually the old patterns reassert themselves because neurologically they’re still stronger.
the new behavior requires constant conscious effort. the old behavior is automatic.
and you cannot maintain conscious effort indefinitely. your prefrontal cortex will tap out. your subconscious will takeover.
this is what people interpret as “losing motivation” or “losing discipline.”
but it’s not about motivation. it’s about the relative strength of competing neural pathways.
you didn’t lose anything. you just ran out of metabolic resources to keep fighting your brain’s default programming.
the solution isn’t more willpower. it’s understanding the mechanism of change and working with it.
you need to:
build the new pathway through consistent repetition
weaken the old pathway by removing environmental cues and avoiding the behavior
shift identity through accumulated behavioral evidence
leverage neuroplasticity triggers like focused attention and productive discomfort
give your brain time to consolidate changes through adequate sleep
be patient with the process because myelin takes time to build
and most importantly, you need to stop expecting change to feel good or easy.
if it feels easy, you’re not actually changing anything. you’re just running on existing pathways.
real change feels uncomfortable because you’re operating in a zone where your current neural configuration is insufficient.
that’s not a bug it’s simply the feature.
NEW YEAR, NEW NEURAL ARCHITECTURE
so it’s a new year and yeah, maybe you want to be different.
but understand that “new me” isn’t a decision.
your brain right now is the physical embodiment of everything you’ve done up until this point.
every habit, every thought pattern, every behavior is encoded in neural pathways that have been reinforced through repetition.
you can’t just wake up on january 1st and be a different person because your brain is still the same brain it was on december 31st. flipping the calender doesn’t mean it flips your brain. you’re still running on old software.
same neural architecture. same myelinated pathways. same predictive model.
but what you can do is start the process of rewiring.
you can understand that change is neurological. that it requires time, repetition, and deliberate effort in the face of discomfort.
you can stop blaming yourself for “lacking discipline” and start working with the actual mechanism of how brains change.
you can be strategic about environment, attention, identity, and behavioral evidence.
and you can be patient with the process while still being consistent with the effort.
and i promise you it will change because you consistently perform the behavior until the new pathway is stronger than the old one.
until the new identity has more behavioral evidence than the old one.
until your brain’s predictive model updates to reflect who you’re actually being instead of who you used to be.
and that takes longer than january. might take all year. might take multiple years.
but if you understand the mechanism, you can actually make it happen instead of just hoping it happens.
new year?
sure.
new you?
only if you’re willing to put in the neurological work.
p.s. i’m going crazy with content this month. posting every single day in january, switching between free and paid posts. if you're getting value from the free stuff, the paid tier is legitimately 10x deeper. i’m giving information i pay hundreds for $7/month right now but that's going up soon. this january is packed with generational knowledge that will shift how you think about everything. lock in while it's still cheap. click this if your looking to upgrade

Long read but i felt it myelinate my focus pathway 😭😭 you're a beast tho fr
Great piece on the friction of change. One nuance I've found helpful in my own work in neuroscience is distinguishing between the 'path' and the 'pavement.'
You focus heavily on myelination, which is the pavement—it makes the signal fast and automatic. But the creation of the new habit is actually synaptic plasticity. It's the act of hacking a path through the woods with a machete. It’s slow and exhausting not because the signal is un-insulated, but because the connection is biologically weak. We have to blaze the trail (synaptic change) before the brain is willing to invest the energy to pave it (myelination). The struggle isn't just lack of speed; it's the metabolic cost of construction.
