Why does commitment scope fail?

The most common reason commitment scope fails: Over-scoping in the other direction — making the commitment so narrow and rigid that any deviation feels like failure. You commit to 'write exactly 500 words at 6:00 AM in the kitchen chair using the blue notebook' and then skip it entirely because you woke up at 6:15 or the kitchen was occupied. Effective scoping creates a clear target with reasonable boundaries, not a brittle ritual that shatters on first contact with reality. The goal is specific enough to execute, flexible enough to survive normal variation.

The fix: Take your single most important active commitment — the one you most want to follow through on. Write it down exactly as it currently lives in your head. Now score it on the five dimensions of scope: Does it specify when? Where? How much? How long? What counts as done? For every missing dimension, add it. Rewrite the commitment as a scoped action statement with all five dimensions present. The rewritten version should be something a stranger could verify without asking you any clarifying questions. If it isn't, it's still too vague.

The underlying principle is straightforward: Commit to small specific actions rather than large vague goals.
