Why your brain won’t let you build new habits (and what to do about it)

Habits are tricky, aren’t they?

You start with enthusiasm, stacking one positive change after another. But then it happens—you miss a day. Then another. Before you know it, a week has passed. Then a month. And just like that, the habit you were so proud of is gone.

Worse yet, it feels like you’re sliding backward:

• Instead of losing 10 kg, you’ve gained 3.
• Instead of a tidy home, the laundry’s taken over.
• And that inbox you swore to organize? Now it’s creeping past 1,000 unread emails.

Sound familiar? If so, you're not alone—and there’s a way to break this cycle.

But let’s get one thing straight first: this isn’t your fault.

In fact, it’s nobody’s fault—but if we’re pointing fingers, let’s blame your brain. When we try to build and stack new habits, we often overload our brain’s capacity to adapt. The brain is not lazy; it’s just doing its job. Ironically, by doing its job so well, your brain is shooting itself (and you) in the foot.

Why Your Brain Resists New Habits

Job 1: The Dopamine Hunt.
Every time you start a new habit, your brain rewards you with a shot of dopamine—the feel-good chemical. At first, this is great! But dopamine is addictive. Your brain starts craving it and comes up with hundreds of little ways to “improve” and stack more habits just to keep that dopamine train rolling.

Job 2: Energy Conservation.
While your brain is chasing dopamine, it’s also trying to conserve energy—its primary job is keeping you alive, after all. Adapting to new behavior requires a lot of mental energy. Eventually, your brain hits its breaking point. The fuel runs out. The parade stops.

Why Habit Overload Leads to Burnout

This is where overload kicks in.

Your brain, now worn out, shuts down your new habits altogether. It’s desperate for recovery, so it seeks rest and calories instead. That’s why you’ll find yourself eating poorly, letting the house fall into chaos, or ignoring tasks you once handled with ease.

The good news? This is fixable. And it’s easier than you think.

The Fix: Timing Is Everything

The mistake we make isn’t building new habits—it’s stacking them too soon. A habit isn’t just something you practice; it’s something you do automatically and miss when you don’t.

Take brushing your teeth, for example. If you shower midday, chances are you’ll brush your teeth too. It’s almost harder not to do it. That’s a habit.

The Key to Building Lasting Habits

The solution is simple: build one small habit at a time and keep it small long enough—long enough for it to stick.

When you can do it effortlessly, without reminders, for about a month, then you’re ready to stack another. This strategy prevents overload and protects your brain’s energy reserves, giving you the momentum to create lasting change.

So why is this important? Right now, you’re probably doing too much, too fast, and burning yourself out. And that’s good—it means you care. You have the resources and the motivation to improve. Now, all you need is to pace yourself.

Your next step: pick one small change and stick with it.

For me, that was as simple as: Go to the gym -> Do two exercises -> Go home.

It was a game-changer, and I hope your next small habit will be a game-changer for you too. Start small. Keep going. The results will surprise you.

To Summarize

We fail at building habits because we overload our brain.

• On one hand, our brain chases the dopamine dragon, stacking more and more habits onto our to-do list.
• On the other hand, when it burns out, it shuts down the entire habit chain.
• Things often get worse, as recovery time pulls us below even our baseline behaviors.

The key to fixing this? Keep your habits small and stick with them for longer periods of time.
