How to become a dangerously good thinker (anyone can do it)
What quietly happened to your brain without you realising, and how to fix it.
It’s 5 am and your alarm just went off.
Your eyes are groggy, the room is cold and dark. But you get up.
You walk into the bathroom and look in the mirror.
And you don’t recognise who’s staring back at you.
Who the fuck is this?
You notice the wrinkles on your face. Where did they come from?
Maybe you notice your hair thinning or more greys have mysteriously appeared.
You start wondering where the time has gone.
Where did the last 10 years go? When did I get so old?
Today, you have a choice to make.
A year from now, one of two versions of you will exist.
Which version will it be?
In this essay, I’m going to show you three things that quietly happened to you without you realising.
Then, I’ll show you the one thing that reverses all three, and what to do about it starting today.
Let’s dive in.
I - You lost the space to think without noticing
You became incapable of waiting.
Not in the patient-virtue sense. In the neurological sense.
All of humanity’s problems stem from man’s inability to sit quietly in a room alone. - Blaise Pascal, 1654
The human brain is wired for the easy path. By design.
Evolution only cared about one thing: keeping you alive long enough to pass on your genes. The shortest path to calories won, always.
You still run on that wiring despite living in the 21st century.
The modern world turned that wiring into a liability.
Think back 30 years (if you’re old enough). That would be 1996.
The Spice Girls launched their debut single. President Clinton got re-elected. Princess Diana and Prince Charles’ divorce was finalised. IBM’s Deep Blue supercomputer beat the world chess champion (Garry Kasparov) in a classic game.
It was a time when we had to wait for things.
Cell phones were clunky and barely anybody had one.
The internet was a new thing and not widely available.
Pizza delivery took 60 minutes (there was no Uber Eats for the young people reading this).
There was no Google Maps: you used a physical map book, plotted your route, loosely memorised your ride, and off you went.
When you had a question you couldn’t answer, you waited to ask someone who knew, or you went to the library to figure it out.
Waiting was the space where thinking happened.
Today, that space is gone.
You order something online and refresh the tracking page three times before it ships.
You honk at a car that hasn’t moved for half a second when the light turns green.
You overtake a cyclist into oncoming traffic because 10 seconds behind a bike feels like an eternity.
You’ve become incapable of waiting for anything, including your own thoughts.
I’m not complaining about “kids these days.”
I’m describing a nervous system that’s been retrained. Every notification, every autoplay, every infinite scroll tells your brain the same thing: stimulation is always available, and stillness is a problem to be solved.
Think about your own behaviour.
You get into a lift and immediately pull out your phone.
When you stand in a queue at the supermarket, you pull out your phone.
When you wait for a coffee, you guessed it, you pull out your phone.
Even during a quiet evening at home, all you’re thinking about is the list of improvements you need to make.
There may be a beautiful sunset, but instead of taking it in, you’re taking a picture of it.
You literally cannot sit still long enough to finish a thought.
But losing the ability to sit with a thought is only half the problem. The other half is what you filled that silence with - information that rewards you for staying shallow.
II - Confusing access with understanding
We live in a time when more information is available than at any other period in human history. You can pull up information about anything from a device in your pocket.
And yet.
The average person checks their phone 144 times a day and can’t read a book chapter without reaching for it.
We are the most distracted and shallow-thinking generation ever.
The paradox is easy to explain.
Access to information is not the same as understanding.
Scrolling through 10 summaries of a book is not the same as reading it.
Watching a 60-second clip about macroeconomics is not the same as knowing what a bond yield is.
You know just enough to not know how little you know.
Your brain confuses exposure with comprehension. A cheap dopamine hit from a new fact, another dopamine hit from a hot take, another from a reply you sent without thinking.
You get rewarded for staying shallow because going deep doesn’t produce a notification.
It’s the reason the loudest person in the room is usually the one who’s done the least reading.
Mark Twain put it more bluntly:
Most men die at 27; we just bury them at 72.
He meant that most people stop growing early. They coast. The body keeps going, but the mind checked out decades ago, somewhere between the third scroll and the fifth app switch.
You probably know people like this in your life. I certainly do.
The easiest way to spot them: they think they know everything, yet they stopped learning decades ago.
Reflect for a moment about the change the world has experienced since 1996.
Now imagine what the future will look like.
The biggest minds at the forefront of technology anticipate that we’ll see more change in the next 10-15 years than we did in the past 100 years.
The 20th century already compressed an enormous amount of progress (electricity, cars, planes, computers, internet, antibiotics).
If you want to keep up with the world of 2050, you’ll need to reinvent yourself again and again.
Both of these have the same thing in common.
And once you see it, everything in this letter reorganises itself around one idea.
III - Thinking was something you did between gaps
You were never a person who did thinking (nobody is).
Thinking isn’t something you schedule.
It happens in the gaps: in the queue, in the shower, on the drive home, in the 90 seconds before the meeting starts. That’s where a thought grows.
You didn’t get lazier, and you didn’t get dumber.
You just deleted the gaps.
Every one of them is now deliberately filled by companies that employ very smart people to make sure you never have them again.
The lift. The queue. The traffic light.
The sunset you photographed instead of watching.
Each of these was a gap, and each one is gone.
It took me years to work this out: you can’t get the gaps back by trying to have them.
Sitting quietly and intending to think produces nothing but a list of things you forgot to do.
The gaps were forced on you by a world that made you wait (which, in hindsight, was a good thing).
You need something that forces the gaps again.
And there’s exactly one thing left that does.
You can’t write faster than you can think.
That’s it. It’s tragic how simple it is.
Writing is the last activity in modern life that physically can’t be done at the speed of consumption.
The blank page won’t get filled until a thought arrives.
When you stopped writing, you stopped thinking.
Writing forces you to wrestle with an idea long enough to examine it. You can’t fake clarity on paper the way you can fake it in your own head.
A half-formed idea feels complete until you try to put it into words. Then holes appear.
Which is why most people avoid it, because it’s uncomfortable. They end up staying in the fog and mistake it for intelligence.
This applies to any act of creation.
Drawing. Building something with your hands. Teaching a concept to someone else. All of it requires you to externalise what’s in your head, and the external version is always messy.
The mess is the thinking.
Think about the people who built the first rockets.
They didn’t have the internet, or YouTube, or a Substack essay telling them how to do it.
They had pen, paper, and the willingness to fail hundreds of times until the thing stopped exploding on the launchpad.
Failure was information.
Every explosion taught them something the previous one didn’t.
This is what thinking looks like when no one is giving you the answer.
These three forces - the silence you lost, information you mistook for thinking, the writing you stopped doing - are not just changing your habits.
They are physically reshaping the organ inside your skull.
IV - The brain you are building (or not)
A little girl asks her dad what he does for work.
He replies that he teaches adults how to draw.
She looks puzzled and asks, “Did they forget?”
There’s a physical reason writing does this, and a physical reason its absence is costing you.
Neuroplasticity means your brain reshapes itself in response to what you demand of it.
If you demand nothing, it shrinks. If you demand something hard, it grows.
You can literally reprogram yourself.
The hippocampus - responsible for memory, learning, and focus - is especially responsive.
A recent study found that resistance training directly slows brain aging at the cellular level.
Other studies caught the same pattern: twelve weeks of strength training, and the hippocampus and precuneus - the two regions that reliably shrink as we age - stop shrinking.
You are not just building muscle.
You are building the physical infrastructure of attention.
Think of it like any other muscle. If you stop using your legs, they atrophy.
Your brain follows the same rule, but the atrophy is invisible.
You don’t notice it until you try to focus on a long piece of writing (like this one) and give up after three paragraphs.
(Congratulations if you made it this far)
Or until you sit down to write something and realise you have nothing to say that you haven’t borrowed from someone else.
Every time you switch tasks or check a notification mid-thought, you are doing half a rep and walking away.
A little atrophy, repeated thousands of times over years.
The result is a brain that can consume but cannot create.
You can react, but you cannot reflect.
You know a lot of things and understand almost none of them.
The path of least resistance is a terrible teacher.
It asks nothing of your brain except that it stay awake.
The damage is real, but so is the reversal.
The same neuroplasticity that lets your brain atrophy from neglect is the mechanism that lets you rebuild it.
V - Thinking on paper
It’s often said that the top 1% of people think on paper.
Writing forces you to externalise your thoughts.
And if you like drawing pictures or doodling, do more of it. Circles, boxes, arrows; they all work.
Three types of processing happen when you draw:
Semantic → thinking about the meaning of what you’re drawing
Visual → creating a mental picture
Motor → physically moving your hand to create the image
Handwriting forces friction.
When you type your notes, you produce more words.
When you write your notes physically, you can’t keep up.
The inability to keep up is what makes it powerful. Your brain is processing vs. staying on the surface.
Writing is how to develop metacognition (the ability to think about your thinking).
When you write something in your own words, it forces the transformation of knowledge. You learn and retain way more than writing things down verbatim.
Think about the last book you read: how much of it do you remember?
I’m willing to bet not much.
Next time you’re reading a book, try this: take your pen and paper, and write notes in your OWN words as you work your way through the chapter.
You should also highlight keywords in your book and write on the pages themselves. Books were meant to be read and to learn from. The author would thank you for it.
Yes, it will be slower, but that’s the point. You’ll retain way more this way.
There are other learning concepts like spaced repetition and active recall, but that’s for another day.
For now, the point is this: write on paper.
VI - How to fix your brain
I judge you unfortunate because you have never lived through misfortune. You have passed through life without an opponent. No one can ever know what you are capable of, not even you. - Seneca
Here are 3 steps you can implement, starting today.
Step 1: Less screen time
This is not a digital detox retreat or a promise to throw your phone into the ocean.
It’s much simpler.
Pick one hour a day when you leave your phone in another room.
Not on silent.
Not face down.
Gone.
In that hour, your brain has no choice but to just “be.”
It’s called the solitude technique: 30-60 minutes alone, no distractions, letting the brain shift from reacting to creating.
Your ideas that have been buried under notifications will start to surface.
Messy things will begin to make sense.
Go for a walk without your phone. You’ll be fine.
Step 2: Write something
Write anything.
Dump your thoughts on paper. Yes, paper.
No structure, no editing. Just get it out.
Write about your day.
Write about an idea you disagree with and why.
Write about anything you’re interested in.
Writing is uncomfortable because it forces you to confront the gap between what you think you know and what you can actually articulate.
Step 3: Make it hard enough to hurt
Freewriting will get you started, but it won’t get you far.
A brain dump is a gap you opened but haven’t yet worked in.
So raise the demand.
Take one thing you believe (something you’d defend without hesitating), and write the strongest possible case against it.
A proper version that an intelligent opponent would make.
You’ll discover, somewhere in the fourth paragraph, that you can’t do it.
That you don’t understand your own position well enough to attack it.
It’s not a failure.
It’s the first honest look you’ve had at the inside of your own head in years.
Neuroplasticity only fires when demand exceeds current capacity.
Comfortable doesn’t reshape anything.
It doesn’t take much. 1% past comfortable is enough, but it has to be past it.
Do that once a week, and you’ll know more about what you think than most people learn in a decade.
One year from now
You’re back in the bathroom, looking in the mirror.
The version of you that did nothing will wake up, see the same wrinkles, and still wonder where the time went.
Maybe you’ll vaguely remember the Mark Twain quote in this essay as something you should have listened to.
It’s just another thing you didn’t act on.
Then there’s the version of you that chose the hard path.
You’ll wake up, see the same wrinkles, and know exactly where the time went.
It went into the hundred mornings you sat at the kitchen table with a pen and a blank page, trying to turn fog into sentences.
The year you spent learning a new language after the kids went to bed.
The first time someone told you your writing changed how they think.
Camus wrote that “struggle itself is the source of joy, and the possibility of finding meaning inside the struggle is enough to fill a person’s heart.”
The joy doesn’t arrive after the struggle.
It lives inside it.
The future version of you cannot exist without the current version being the catalyst. Read that again.
Nobody is coming to do the hard part for you.
All you need is a pen and a piece of paper.
You now know what to do.
You probably knew most of it before you started reading.
The pen and paper have been sitting there the whole time.
And you still won’t do it.
Because the gaps are gone.
You don’t have any left.
You’ll write for four days.
Then something happens, or you get distracted.
And your phone is right there.
The problem is structure, not motivation.
You’re trying to rebuild the one thing your calendar is designed to eliminate.
That’s what I built The Refactor for.
It’s a programme for people exactly in your position.
Someone completely without gaps.
It doesn’t teach you to write. It rebuilds the conditions in which thinking is possible again: where the hour comes from, what protects it, what happens when work tries to take it back, and how you keep it after the novelty wears off.
Because the pen and paper were never the hard part.
