Tiny
Habits

The small changes that change everything. A Stanford scientist's proven system for making any behavior stick — permanently.

"Start so small it feels obvious."

The Philosophy

You are not the problem.

BJ Fogg spent two decades researching why people struggle to change — and discovered the answer isn't willpower.

"If you're struggling to change, don't blame yourself. The problem isn't you. The problem is your system for change."

Why willpower fails

Willpower is a depletable resource. Relying on motivation to sustain habits means you'll only succeed when you feel like it — which is rarely. Fogg's system removes motivation from the equation entirely.

The compound effect of tiny

A habit that takes under 30 seconds meets no resistance. Practiced daily, even the smallest behavior reshapes your identity. BJ Fogg calls this "the gateway habit" — tiny becomes the seed of transformation.

🎯
Anchor it

Use what already exists

Every reliable habit you already have — brushing teeth, morning coffee, starting the car — is an anchor. Tiny habits attach to these without disrupting your day.

Make it tiny

Smaller than you think

Don't start with "run 3 miles." Start with "put on running shoes." The new behavior must be so small it requires zero motivation. If it feels ridiculous, you're doing it right.

🎉
Celebrate always

Feeling good is the signal

Immediately after your tiny habit, do something that makes you feel good. A fist pump, a smile, a quiet "yes." That feeling is what wires the habit into your brain.

The Formula

B = MAP

Every human behavior is explained by three factors. Fogg spent 20 years at Stanford proving this model — and discovering what actually moves the needle.

B
Behavior

The action you want to make automatic

=
M
Motivation

Your desire to do the behavior

+
A
Ability

How easy the behavior is to do

+
P
Prompt

A cue that triggers the behavior

Most people focus on M

Motivation is unreliable. High motivation feels good but fades. Building on motivation means your habits only survive when you're already energized.

❌ Motivation-first approach
Fogg focuses on A

Maximize Ability by making the behavior tiny. When the behavior is effortless, even minimal motivation is enough to trigger it — every single day.

✓ Ability-first approach
P is the missing key

Without a prompt, behaviors don't happen — no matter how motivated you are. Anchoring to an existing habit provides an automatic, built-in prompt.

What resonated

Community Insights

"You are not the problem. The system around you is the problem. When you know how to create the right system, change becomes natural and automatic."

Fogg spent two decades at Stanford collecting data from 40,000+ participants — and the pattern was always the same: people don't fail because they lack willpower.

resonated

"Motivation is like a wave — it rises and falls. Tiny habits don't rely on motivation. They rely on an anchor that already exists in your life."

The anchor is the secret weapon. Instead of waiting to feel ready, you attach the new behavior to something you already do without thinking.

resonated

"Celebration is the most overlooked part of habit formation. When you feel good immediately after a tiny habit, your brain marks it as something worth repeating."

Fogg calls this 'Shine' — the feeling you create on purpose right after your tiny habit. It is the direct mechanism by which neurons wire together.

resonated

"The secret of Tiny Habits is this: people change best by feeling good, not by feeling bad. Guilt and shame never create lasting habits. Celebration always does."

resonated

"Start with a behavior so tiny it almost seems ridiculous. Not a one-mile run — just the act of putting on your running shoes. That's your tiny habit."

If you want to build a meditation practice, your tiny habit might be to sit on your cushion for two breaths. The behavior will naturally grow once it is wired in.

resonated

"Every habit you have — good or bad — follows the same three-step pattern: Anchor, Behavior, Celebration. Understand the pattern, and you understand how to change."

resonated

"Think of behavior design like a garden. You don't force a seed to grow. You create the right conditions — and let growth happen on its own schedule."

resonated

"An anchor is any habit you already do reliably. Morning coffee. Brushing teeth. Starting your car. These are the natural pegs you hang new habits on."

Action Steps

The habits most worth starting, voted by the community.

01

Run my three morning tinies

Complete each of your three morning tiny habits on its anchor. Three small wins before the day gets loud.

I'll do this
01

Write your first recipe

Write one recipe on paper: After I [Anchor], I will [tiny Behavior]. Then I celebrate. Put it where you will see it — writing makes it real.

I'll do this
02

Find your three anchors

Spend one day listing habits you already do automatically. Circle three solid ones. These become the anchors for your first tiny habits.

I'll do this
03

Shrink it until it's obvious

Shrink the new behavior until it takes under 30 seconds and feels almost too easy. Tiny is the design goal, not a temporary compromise.

I'll do this
04

Design a celebration you mean

Pick a celebration that creates a real spark — a quiet yes, fist pump, or smile. It must feel genuine, or your brain will not wire the habit in.

I'll do this
05

Stack three morning habits

Choose three automatic anchors (coffee, teeth, sit at desk) and attach one tiny behavior to each. Write all three recipes before you start the week.

I'll do this
09

Run one Anchor → Behavior → Celebration

Once today: hit the Anchor, do the tiny Behavior, celebrate immediately. Keep it small enough to succeed on a bad day.

I'll do this
06

Track with a single dot

After each tiny habit, put one dot in a notebook. Just a dot — visual proof without turning tracking into a project.

I'll do this
10

Do the shrunk version

Complete only the under-30-second version you designed — floss one tooth, put on shoes, open the notebook. No upsizing required.

I'll do this
07

Let the habit grow naturally

Write your growth rule: keep the tiny version until it feels automatic; only then let it expand. Do not force size before the habit is wired.

I'll do this
🌿

You are not the problem. The problem is your system. Tiny habits give you the right system.
