The Habit Designer
Design the conditions, not the willpower.
The habit
The second box does more work than it looks like. “Read every day” is a task you can fail; “someone who reads” is a person you can be, and one missed evening doesn’t revoke it.
Already tried and it didn’t stick?
Pick what actually happened. A habit almost never fails at all four laws — it fails at one, and the symptom tells you which.
A habit with no cue is a wish. Give it a time and a place, or bolt it onto something you already do without thinking — the existing habit becomes the alarm clock.
Without it: You forget, or you 'never got round to it'.
Implementation intentions — the "I will [X] at [time] in [place]" form — come from Peter Gollwitzer's research, which found that specifying when and where roughly doubles follow-through versus intention alone.
Your habit, in one sentence
Name the habit above and this writes itself.
Next: I will do it at (law 1, make it obvious). A time and a place. "In the morning" is not a time and "at home" is not a place.
The Four Laws of Behaviour Change are James Clear’s, from Atomic Habits. Implementation intentions come from Peter Gollwitzer’s research and temptation bundling from Katherine Milkman’s. One deliberate change: the fourth law here is built on “never miss twice” rather than a streak to protect — nothing on this site counts streaks, because a counter turns one missed Tuesday into a reason to stop.
What you type here is saved automatically — on this device, and to your account if you have one.
