The Atomic Habits cheat sheet, on one page

I have built a habit tracker, which means I have read more habit books than is reasonable. Atomic Habits is the one whose ideas keep surviving contact with real users, mostly because James Clear resisted the urge to make it complicated. The whole framework fits on a page.

So here it is on a page. This is my own summary in my own words, not a copy of Clear’s materials. If you want his version, he gives it away on his site and you should get it from him.

The four laws of behaviour change

The premise is that every habit runs a four-step loop: a cue, a craving, a response, and a reward. Each law targets one step. To build a habit, you make each step easier.

1. Make it obvious

Habits start with a cue you notice. Most failed habits fail here, not at the effort stage. You did not decide against flossing, you just never saw the floss.

Put the thing where you will trip over it. Guitar on a stand, not in a case under the bed. Running shoes by the door. Write the intention down with a time and a place attached: I will [habit] at [time] in [place]. Vague intentions lose to specific ones, and it is not close.

2. Make it attractive

We do things we expect to enjoy. Pair the habit you want with something you already like, which Clear calls temptation bundling. Podcasts only at the gym. The good coffee only while you write.

The stronger version is social. You will pick up the habits of the people around you almost without deciding to, so being in a group where your target habit is normal does more work than any amount of willpower.

3. Make it easy

This is the one people skip, and it is the one that matters most. Reduce the friction between you and the first action until the first action is almost free.

Lay the clothes out. Prep the thing the night before. Cut the habit down to a version so small it feels like cheating. The goal early on is not progress, it is showing up often enough that showing up stops being a decision.

4. Make it satisfying

What gets rewarded gets repeated, and the reward has to arrive close enough in time that your brain connects it to the action. The problem with good habits is that the payoff is months away. Flossing today does nothing you can feel today.

So you borrow a reward. Marking the day off is the cheapest one available, which is the entire reason habit trackers work and the entire reason I built one.

The inversions, for breaking a habit

Run each law backwards and you get the framework for quitting something.

• Make it invisible. Remove the cue. The snacks leave the house, the app leaves the home screen.
• Make it unattractive. Get specific about what the habit actually costs you, not in the abstract but this week.
• Make it difficult. Add friction. Log out. Use a blocker. Leave the console cable in another room.
• Make it unsatisfying. Attach a cost to slipping, ideally one somebody else can see.

Habit stacking

The formula is after [current habit], I will [new habit]. You already have a reliable chain of daily actions, so bolt the new one onto an existing link instead of trying to find it a slot of its own.

After I pour my coffee, I write one sentence. After I brush my teeth, I lay out tomorrow’s clothes. The existing habit is the cue, which means you have solved law one for free.

One caution from watching people use this: stacks break at the weakest link. If the anchor habit is itself unreliable, the new habit inherits that unreliability. Anchor to something you have done every day for years, not something you started last month.

The two-minute rule

Scale the habit down until the entry version takes under two minutes. Not “read thirty pages” but “read one page”. Not “run five kilometres” but “put the shoes on”.

This sounds like a trick to get you started so you do more, and sometimes it is. That is not the real point. The real point is that the two-minute version is the habit, and the volume comes later without you having to negotiate with yourself every morning.

Print it

If you want the four laws next to a grid you can actually fill in, the free printable habit tracker builds a sheet with your own habits on it. Monthly grid, weekly grid or a circle, no email required.

And when you miss a day, do not start the sheet over. A month with four gaps is still twenty-six days you showed up. Throwing the page away is how one bad day turns into a lost month, which is exactly the problem Streak Repair exists to solve in the app.
