The four laws

The whole book hangs on four questions, and each has a reverse. To build a habit you go down the left-hand column. To break one, you invert each of them.

The same four levers, two directions

The lever	Building a good habit	Breaking a bad one
The cue	Make it obvious – the running shoes are out	Make it invisible – the phone on another floor
The craving	Make it attractive – tie it to something you like	Make it unattractive – look at what it actually costs you
The effort	Make it easy – as few steps as possible between you and the act	Make it hard – put friction in the way
The reward	Make it satisfying – something you feel straight away	Make it unsatisfying – let it cost something to skip

Note that none of the rows is about wanting it enough. They are about arranging the situation so the choice is easy before you are standing in it – and that is the whole difference from relying on motivation.

The identity beneath the habit

Clear's argument is that most people start at the wrong end. They set a result, find a method, and hope that in the end it will make them a different sort of person. He turns it round:

Three layers – and which one you start with

OutcomesWhat you want to achieve. “I want to lose five kilos.” This is the layer most people start on.

ProcessWhat you do. The training programme, the routine, the system.

IdentityWho you believe you are. “I am someone who trains.” Habits that stick, stick here.

The difference shows up the day something goes wrong. If the goal is five kilos, a missed session is a defeat. If the starting point is that you are someone who trains, it is only a day without training – and someone who trains goes tomorrow.

One per cent

The number has become the book's trademark, and it is worth seeing what it actually says.

One year of one per cent

This is the sum 1.01 to the power of 365 against 0.99 to the power of 365 – a picture of how small differences accumulate, not a measurement of anything. The most useful thing about the curve is its shape: the first third looks almost flat. That is where people give up, because nothing is showing yet.

Two weeks, two lines

The wavy line is not a measurement of anything – it is an illustration of a pattern most people recognise. What matters is what happens at the low points: that is where a habit resting on motivation falls away. A fixed time of day does not care where the curve sits that morning, and that is the whole reason it works better.

Missing once is fine. Never miss twice.

Why the rule is shaped this way: it is not the lost day that topples a habit – it is the day after, when “I have already broken the run” becomes the reason to skip again. The rule moves attention away from what went wrong and onto the one choice that actually decides it.

Key points

Make the habit obvious, attractive, easy and satisfying – and invert all four for bad habits.
Build the identity first – you are someone who trains, not someone trying to train.
Attach the new habit to one you already have, like brushing your teeth or the morning coffee.
Shrink the habit to two minutes. Early on, showing up matters more than performing.

Key points (cont.)

Missing once is fine. Never miss twice.
A good system saves willpower – and willpower is a limited resource.
