Plan — make an if-then plan for the obstacle

Pre-decide your response: "If [obstacle], then I will [effective action]."

Why it works

The plan is an implementation intention bound to the obstacle you just identified. By pre-deciding "if obstacle, then response," you create a cue-action link that fires automatically when the obstacle appears, sparing you from having to summon willpower in the moment. WOOP’s power comes from pairing this plan with the contrasting that made the obstacle salient.

How to do it

1. Write "If [the obstacle happens], then I will [a specific action]."
2. Choose a response you can actually execute in the moment, not an aspiration.
3. Rehearse the if-then so the cue reliably triggers the action.

Evidence

Implementation intentions are among the most robustly supported behavior tools, with a large meta-analysis showing a medium-to-large effect on goal attainment; WOOP combines them with mental contrasting, and the combined protocol has its own supporting trials. (rct)

Plans fade if the obstacle is vague or the response is unrealistic; the if-then must name a concrete cue and a doable action.

Common mistake

Writing a plan as a generic intention ("I’ll try harder") rather than a specific if-then tied to the exact obstacle, so no cue ever fires.
