Atomic Habits: Creating Better Habits

Atomic Habits is one of the most prominent self-help and personal development books on the market. Naturally, I bought it and let it sit on my desk for two years before digging into it.

I’m not against the personal development genre. Most of the books on my shelf fall into that category. Still, after a while, they start to feel repetitive. Different titles, slightly different frameworks, same general message: change your habits, change your life.

When I finally read Atomic Habits, I had a strange realization. I already knew most of what was in the book.

Make good habits easier. Make bad habits harder. Change your environment. Reduce friction. Stack behaviors.

All of it makes sense. None of it is revolutionary.

What stood out to me wasn’t the tactics—it was the emphasis on identity.

Who Are You?

All of us identify ourselves in some way.

I tend to think of myself as strong-willed, reliable, and someone who genuinely wants to help people move with purpose. That internal narrative shapes how I show up. And how I show up reinforces that narrative.

Your habits shape your identity, and your identity shapes your habits.

That loop is powerful.

Habits aren’t random behaviors floating in space. They are expressions of how you see yourself. If someone identifies as “bad with money,” they will unconsciously make financial decisions that confirm it. If someone identifies as “not athletic,” they will avoid situations that challenge that belief.

The same applies to health and movement.

If you believe you are stiff, fragile, broken, or “just getting older,” your actions will align with that story. You will hesitate before loading weight. You will skip mobility work. You will rationalize inactivity. Not because you are lazy—but because you are acting in alignment with who you believe you are.

Identity quietly drives behavior.

The Nail-Biter Story

There’s a story in the book about a man who could never stop biting his nails. He tried willpower. He tried awareness. He tried telling himself to stop.

Nothing worked.

Eventually, his wife booked him a manicure. After seeing his hands cleaned up and shaped properly for the first time in years, something shifted. He liked how they looked. More importantly, he no longer saw himself as a nail-biter.

He began to see himself as someone who took care of his hands.

And he stopped biting them.

It wasn’t discipline that changed him—it was identity.

I read that story, put the book down, and booked my first manicure at thirty-five. I can’t say I love the process, but I appreciate the result. What stuck with me wasn’t the cosmetic change. It was the realization that small shifts in self-perception can completely alter future behavior.

Why Identity Matters More Than Motivation

Most people think they need more motivation.

They don’t.

Motivation fluctuates. Identity stabilizes.

In training, I’ve seen this play out for years. The person who says, “I’m trying to work out more,” behaves very differently than the person who says, “I train.”

The first person negotiates constantly. They’re looking for the right mood, the right timing, the right circumstances.

The second person shows up—not because they feel like it every day, but because it’s congruent with who they believe they are.

When identity changes, behavior becomes less of a debate.

That doesn’t mean it becomes easy. It means it becomes aligned.

Identity and Movement

This is where the book hit home for me professionally.

Many people walk into a gym already carrying a limiting identity.

“I have bad knees.” “My back is just messed up.” “I’m not flexible.” “I’m not built for this.”

Those statements sound factual, but they’re often stories reinforced over time. And once someone adopts them as part of their identity, their behavior adjusts accordingly.

They avoid ranges of motion. They fear loading. They stop challenging their body.

Over time, the story becomes self-fulfilling.

But the opposite is also true.

When someone begins to see themselves as “a person who trains intelligently” or “a person who takes care of their joints,” their decisions shift. They become more consistent. They tolerate discomfort better. They stop catastrophizing normal soreness. They become proactive instead of reactive.

The external results usually lag behind the internal shift—but the shift is what allows the results to accumulate.

You Become What You Repeatedly Prove to Yourself

Identity is not declared. It’s earned.

You don’t wake up one day and magically become a disciplined person. You become disciplined by acting in alignment with discipline often enough that it becomes familiar.

One session. One better decision. One moment where you choose differently than you did before.

That’s it.

The reason habits compound is not because they are dramatic. It’s because they are repetitive.

If you repeatedly prove to yourself that you are someone who trains, someone who shows up, someone who takes care of your body, that identity strengthens. Once it strengthens, future decisions require less internal negotiation.

That’s how change sticks.

A Practical Way to Think About It

Instead of asking, “How do I get motivated?” try asking a different question.

What would a healthy, strong person do in this moment?

Not in a performative way. Not in a perfectionist way. Just in a directional way.

Then act in alignment with that answer.

You don’t need to feel like that person yet. You need to behave like them often enough that the identity begins to take root.

That’s the quiet power of Atomic Habits.

It’s not about hacks or shortcuts—it’s about recognizing that behavior change starts with how you see yourself.

The nail-biter didn’t stop because he tried harder. He stopped because he stopped seeing himself that way.

If you want better habits—in fitness, in health, in life—start by deciding who you are becoming.

Then prove it to yourself.

Consistently.
