The Goldilocks Rule

Peak motivation occurs when working on tasks right at the edge of your current abilities—not too hard, not too easy.

In Depth

Humans experience optimal engagement when challenges are just manageable. Clear applies this to habit formation: start with a version that's almost too easy (two-minute rule), then gradually increase difficulty as ability grows. This keeps you in the zone of optimal challenge where behavior is engaging enough to be satisfying but not so hard that you quit. It's the key to avoiding both the Valley of Disappointment (starting too hard) and the Plateau of Boredom (staying too easy).

Example

A beginner guitarist shouldn't start with complex solos (too hard, leads to quitting) or simple scales forever (too easy, leads to boredom). Start with simple songs, then gradually increase difficulty as skills improve to maintain engagement.

Common Misconception

The Goldilocks Rule means always staying comfortable, when it actually means working at the edge of your abilities—which is inherently uncomfortable but not overwhelming.

The Two-Minute Rule

Scale down any habit to a two-minute version to overcome starting friction: 'Exercise for 30 minutes' becomes 'Put on workout clothes.'
