For years, I didn't believe my own words anymore.

Not because I was weak. Not because I didn't want it badly enough.

But because I kept making the same promise and breaking it in the same way, at the same time, for the same reasons, and somewhere along the way my brain stopped taking me seriously.

Here's what the cycle looked like.

Monday: clean breakfast, clean lunch, clean dinner. I felt good. Righteous, even.

Tuesday: same. I was doing it. This time was different.

Tuesday evening: the local store had a new flavor of Ben & Jerry's. Just this one thing. I'd been so good. One exception doesn't break a streak.

Except it did. Every time.

Because once I'd made the exception, the logic flipped.

I'd already broken the rule. What was the point of the rest of the week? I'd restart on Monday. That gave me several more days of eating whatever I wanted before it was time to shape up again.

Wednesday of the following week: I didn't know what to make for dinner. I was exhausted from my studies. I told myself I deserved a pizza. I'd been good for two days. Just one pizza.

And I was off the wagon again.

I weighed 107 kilograms (236 pounds). I was 29 years old. The Monday restart cycle had been running for four years.

And The Monday restart wasn't just a diet problem. It was how I approached everything I wanted to change.

The problem was never the ice cream

It's tempting to frame this as a willpower story. The weak man who couldn't resist dessert.

But that's the wrong diagnosis.

And the wrong diagnosis leads to the wrong cure.

Willpower isn't a character trait as much as it's a resource.

And it depletes.

Researchers call it decision fatigue.

Studies show that judges give harsher sentences later in the day, doctors make worse clinical decisions as their shift wears on, and people consistently make worse food choices at night than in the morning.

Not because they're worse people at 9pm. Because the tank is empty.

Every decision you make, what to wear, how to respond to an email, what to say in a meeting, how to handle a difficult moment with your family, draws from the same cognitive pool.

By Tuesday evening, after commuting, going to class, studying , and making a thousand small decisions, that pool was dry.

The Ben & Jerry's wasn't a moral failure.

No amount of wanting it more was going to change the math.

Ask yourself honestly: when do you make your worst decisions? First thing in the morning or last thing at night? After a calm day or a brutal one?

The answer tells you everything about why you've failed before, and why trying harder was never going to be the solution.

The moment I stopped lying to myself

My knees hurt. My back hurt. I avoided mirrors. I avoided scales.

Until one day I didn't.

107 kilograms.

The number stared back at me and I couldn't rationalize it away.

I had promised myself I would stop. Again and again and again. And I hadn't.

So I had to say something I'd been avoiding for years.

I was a liar.

Not to other people. To myself. Repeatedly, systematically, for years.

And somewhere along the way my own promises had become meaningless, background noise I'd learned to tune out.

If I couldn't rely on my own words, what could I rely on?

Not motivation. Motivation is a feeling, and feelings change. Not discipline. I'd tried discipline and it had an expiry date of about 36 hours.

The only thing I hadn't tried was removing the decision entirely.

I found Tim Ferriss's The 4-Hour Body.

The diet was simple: high protein, low carb, the same few meals repeated every day, and one (almost) full cheat day per week where nothing was off limits.

I picked Saturday.

Monday through Friday: four boiled eggs for breakfast, chicken with beans and vegetables for lunch and dinner. Same meals, every day. No decisions required at mealtime. None.

And every craving I had during the week, the brownies, the candy, the pizza, the ice cream, went on a written list. None of it entered my apartment until Saturday. And none of it stayed until Sunday.

Just writing the craving down, knowing Saturday was coming, was enough to get through the moment.

I felt terrible every Sunday. But the system held.

Fifteen kilograms (33 lbs) gone in three months. Combined with long walks with my dog every day.

The system didn't ask me to be a better person.

It asked me to make fewer decisions. And that I could do.

Discipline is what the system looks like before it's built

These days people sometimes tell me I'm disciplined.

660 days of daily burpees. 728 days of publishing something online. 13 weeks of averaging 8,000+ steps a day.

But I'm the same person who couldn't get through a Tuesday evening without ice cream.

I haven't become more disciplined. I've become better at building systems that don't require discipline.

The burpee streak exists because I decided once, not every morning, once, that burpees happen at a fixed time, in a fixed place, in their simplest possible form, with an alarm to enforce it and a backup alarm before bed.

I even decided in advance what the minimum version would look like: something I could complete with a fever, or an injured arm. The decision was made once. It hasn't been revisited in 660 days.

The publishing habit exists because I write on my commute. Five days a week, the commute is writing time. If I'm behind, I republish something old. The habit matters more than the output.

My investment habit exists because an automatic transfer leaves my account the day after my salary arrives and buys more units of my chosen global index fund. I don't decide whether to invest each month.

The system decides. The right choice happens regardless of how I feel about it.

Each system works by the same principle: the decision was made once, in a moment of clarity, and is now protected from the tired, hungry, depleted version of me who would make a different choice.

Build the system in your best moment. Let it run in your worst ones.

What systems actually produce

The results aren't the main product.

The identity is.

After 660 days of burpees, I'm not a man trying to build a workout habit. I'm a man who does burpees. That's not a motivational reframe. It's a factual description of who I've become through repetition.

After months of automatic investing, I'm not a man trying to save money. I'm a man who builds financial density.

After losing 24 kg (53 lbs) in total, I'm not a man on a diet. I'm a man who eats a certain way.

The willpower version of change asks you to fight yourself every day.

The systems version asks you to fight yourself once, to build the system, and then get out of your own way.

The system runs whether I'm motivated or not, whether I feel like it or not, whether the week has been hard or easy.

My daughter is 5.

She already sees me do my burpees daily. I want her to still see that when she's 15. And even 25.

That's what the system is for. Not motivation, but continuity.

The man who restarted his diet every Monday for years didn't eventually succeed because he finally found enough willpower.

He succeeded because he stopped needing it.
​
See you next week.

Warmly,
