How to stop procrastinating: the if-then plan that actually works

Most of us do not procrastinate because we do not know what to do. We know. We just do not start. A simple trick from psychology helps with exactly that gap, and it takes about 30 seconds to set up.

The trick: "When X happens, I will do Y"

Psychologist Peter Gollwitzer calls these "implementation intentions". They sound like this: "When I sit down at my desk, I will open my notes and write one sentence."

A review of 94 studies found a medium-to-large effect on reaching goals (Gollwitzer and Sheeran, 2006). In plain terms, it can move the average person from the middle of the pack toward the top quarter. In one study on exercise, the share of people who followed through went from about 38% to 91% when they made an if-then plan (Milne, Orbell and Sheeran, 2002).

Why it works

Deciding in the moment is hard, especially when you are tired or tempted. An if-then plan makes the decision ahead of time and attaches it to something that will happen anyway. When the moment arrives, the action comes to mind almost on its own, a bit like a habit you built on purpose.

How to write a good one

Rehearse it

Close your eyes and picture the trigger, then picture yourself doing the action. Do this about ten times. It feels silly, but it helps connect the two.

When you are still stuck

Set a timer for five minutes and promise yourself only one thing: do the first small step. Most of the pain of procrastinating is in starting, and once you have started, continuing is usually easier.

The full course includes a plan builder with 10x rehearsal and a 5-minute timer. Start with the free lessons.
