A reader emailed me recently. He wrote that one of his favourite “simple yet non-obvious thoughts” he found on the blog was that I don’t believe in building habits. And I realized something. I’ve mentioned this idea a few times in passing, but I’ve never dedicated a full post or podcast episode to it. So here it is.
Before I go further, I want to be clear about one thing: I’m not saying I don’t believe in consistency. I do. Consistency is what makes everything else possible. What I don’t believe in is the traditional advice on how to get there.
The recipe everyone has read
If you’re even remotely interested in improving your life, you already know the formula. You see a trigger, you change the behaviour, you get a reward. We’ve all read Atomic Habits. We’ve all heard the timeline: 21 days to build a habit. Some say 28. I recently heard someone claim it’s now three months. Whatever the number, the promise is the same: stick with it long enough and the behaviour becomes automatic.
It sounds clean. It sounds simple. It sounds scientific.
And in reality, I have yet to meet a single person who actually achieved consistency this way.
The thought experiment
Think about it for a second. Have you ever met someone who lost a serious amount of weight, learned a new language, built a business, or transformed their career by following the 21-day calendar with check marks on the wall?
I haven’t. Not one. They simply do not exist in my world, and I’ve been paying attention.
What I do know is a lot of people (myself included) who tried it. Day one, motivated. Day two, still going. By day three, the calendar is forgotten and the check marks stop.
And here’s where the logic of it falls apart for me. If this method actually worked, any person who did it once should be unstoppable. They’d build one habit in 21 days, then move to the next, then the next. Within a year they’d have a perfect morning routine, fluent Spanish, a six-pack, a thriving side business, and a meditation practice. They’d be a superhuman. We’d all know their name.
I don’t know that person. Neither do you.
So how do people actually change?
If the traditional habit-building advice doesn’t work, does it mean people are doomed to stay the same? That’s not what we see in real life. People obviously DO change their behaviour. We see it constantly. Someone quits smoking after twenty years. Someone starts running and never stops. Someone walks away from drinking, or sugar, or processed food, and doesn’t go back. They achieve incredible results, and the through-line is some kind of consistent daily or weekly action.
So if it isn’t the 21-day calendar that gets them there, what is it?
I started going through every example I could think of. Every person I knew who had genuinely changed something. I’ve analyzed my own successful behaviour changes of the past. And the same pattern showed up over and over.
The Click Method
I call it the click method. Something clicks in their head, and after that, the old behaviour becomes impossible to continue.
For some people, it’s a diagnosis. They walk out of the hospital with a piece of paper in their hand and they never touch a cigarette again. They quit sugar. They cut out processed food. Done. No 21-day checklists needed. The change took a few minuted after hearing and processing their diagnoses.
For others, it’s a conversation. A breakup. A book. A scene in a movie. One sentence in a podcast interview. If you actually listen to people talk about how they changed, nobody ever mentions the 21-day checkbox method. They tell you a story. They tell you about a moment when something clicked.
After the click, they’re a different person. The old behaviour doesn’t fit anymore. There’s no willpower battle, because there’s nothing left to fight.
Why the click works (and habits don’t)
I’m still figuring out how to self-engineer this click. I have a few ideas. I’m testing them. But here’s what I think is going on.
The click is deeply connected to your value system. When we try to build a habit using someone else’s method, we’re often borrowing the lenses of someone whose values don’t match ours. Their fitness routine, their diet, their morning ritual. The mechanics travel. The meaning doesn’t. That’s why it never sticks.
That’s why a 3rd-generation academic can’t lose weight watching a hot-chick fitness influencer’s TikTok videos. One was raised on being praised for being smart and independent, the other on being praised for being beautiful and liked by men. They both speak English but they speak different value-language. The click is highly unlikely to happen in this situation.
But if you can find a person with a similar value system who already does the thing you want to do (or has stopped the thing you want to stop), and you ask them the right questions, something different happens. You don’t just learn what they do. You start to see the behaviour the way they see it.
You ask, why do you actually go on that boring walk every day? What’s in it for you? And if their answer lands inside your value system, the boring walk doesn’t look boring anymore. It looks obvious. It clicks.
The most underrated book of the 20th century
There’s a book I think did more for public health than almost anything published in the last fifty years, and it gets nowhere near the credit it deserves. It’s The Easy Way to Stop Smoking by Allen Carr.
I personally know four people who quit smoking because of this book (and I don’t know a lot of people who smoke to begin with, so this is a very high success rate). I’ve read it myself. I think it’s a masterclass in the click method.
It doesn’t lean on willpower. It doesn’t put a 21-day calendar in front of you. It doesn’t even spend much time on health, because everyone already knows smoking is bad for you and nobody quits because of that fact alone.
What it does instead is examine the act of smoking from every possible angle. Stress. Relaxation. Identity. Social bonding. Boredom. One by one, it dismantles every excuse a smoker has ever told themselves. Each chapter contains a small click. Huh, I’d never thought about it like that. And by the end, you don’t need to white-knuckle quitting. The whole thing just stops making sense. You smoke your last cigarette and you’re done.
That book is a different category of self-help. It isn’t built on hustle and discipline. It’s built on rearranging how you see the thing.
The math analogy
This same dynamic shows up everywhere. Think about studying a tough subject in school. Math, physics, whatever it was for you. You can grind through problem sets, memorize formulas, push through with discipline, and still feel completely lost. Then there’s that magical moment when the underlying logic clicks. After that, you can apply it to anything. Before the click, no amount of repetition was going to save you.
Behaviour change works the same way. Without the click, all the discipline in the world is wasted effort. With it, the daily action stops feeling like a fight.
What I’d tell you instead
I don’t have all the answers on how to engineer the click on demand. I’m still working on it.
But if you’re trying to start something or stop something, don’t reach for the traditional habit-building tools first. They look logical. They might even be philosophically solid and scientifically defensible. The problem is they don’t work in practice. Have you met the person who got results from them? I haven’t.
Instead, look in the direction of things that actually do work. Listen to interviews. Read the kind of book that takes your behaviour apart and shows you a different angle on it. Find people whose values resemble yours and ask them how they actually think about the thing you’re trying to change.
Something has to click. Once it does, consistency stops being a willpower problem and starts being the natural shape of your day.
That’s the only honest version of habit change I’ve seen work.
