A plan with a when and where
Specifying a cue and response can improve follow-through beyond holding a goal alone.
“Exercise more” leaves the next action to a future negotiation. Peter Gollwitzer’s implementation intentions give the goal a trigger: if situation X occurs, then I will do Y. The format links a visible moment—after lunch, at the station, when the laptop closes—to a prepared response, reducing how much must be decided under pressure.
Meta-analyses find useful average effects, not guaranteed compliance. Plans can fail when the cue is vague, the action unrealistic, or circumstances change; difficult goals also need resources and skill. Yet the small surprise is that wording can alter execution. A goal names a destination. An if-then plan rehearses the doorway through which an ordinary day might actually enter it.

Why this bookTurns behavioural research on goals, stress, and self-control into experiments readers can evaluate themselves.
What to keep in view
Implementation intentions show average benefits with heterogeneous effects and cannot compensate for impossible goals or missing resources.
