The Science of Habits: How to Break Bad Ones and Build Good Ones
Because change isn’t about willpower, it’s about wiring.
We often think habits are a matter of discipline.
“I just need to try harder.”
“I’m so lazy.”
“Why can’t I just stop?”
The truth is:
Habits aren’t just “choices.” They’re patterns your brain has practiced into automatic responses.
That means if you want to change a habit, you don’t need to just “try harder”— you need to understand how habits actually work.
Let’s break it down.
The Habit Loop: Cue → Routine → Reward
Every habit, whether it’s scrolling late at night or exercising regularly, follows a neurological loop:
Cue: A trigger (stress, boredom, time of day)
Routine: The behaviour (e.g., snacking, procrastinating, journaling)
Reward: The brain’s payoff (dopamine hit, escape, comfort)
Once this loop is repeated enough times, your brain runs it on autopilot.
That’s why even “bad” habits feel automatic, and they’re hard to change, even when we want to.
Why Breaking Habits Feels So Hard
Your brain is wired for efficiency, not morality — so it isn’t a matter of weakness.
Your brain doesn’t judge habits as good or bad, it just remembers what gave you relief.
So when you try to break a habit, you’re not just changing behaviour, you’re interrupting a well-grooved circuit that your brain finds comfortable. This is why change feels like resistance at first.
How to Build Better Habits (That Actually Stick)
1. Make It Easy to Start
If the goal is overwhelming, your brain will shut down.
Instead of “I’ll work out 6 days a week,” try “I’ll move my body for 10 minutes after work.”
Lower the barrier to entry
Stack it with an existing routine (e.g., after brushing your teeth)
2. Replace the Routine, Not Just Remove It
Don’t stop the habit, swap it.
If your habit is scrolling when anxious, try replacing it with a grounding activity (like breath work, stretching, or a comfort playlist).
Your brain still gets relief, just from a new source.
3. Make the Reward Meaningful
Habits stick when they feel good now, not just “later.”
Can you make the new habit pleasurable or emotionally rewarding?
Track progress visually. Give yourself permission to be proud. Tie it to your values.
4. Expect Resistance. Stay Curious.
Slipping up doesn’t mean you’ve failed. It means you’re human.
When you “fall off,” ask:
What was I feeling right before?
What need was I trying to meet?
What would a kinder response look like next time?
It takes work, but it’s worth it because it’s about rewiring through compassionate repetition.
Breaking Bad Habits: It’s About Understanding, Not Control
Whether you’re trying to stop doom-scrolling, reduce emotional eating, or start a journaling practice — the key is not to force yourself.
It’s to work with your brain, not against it.
Small actions, repeated with care, create lasting change.
