Identity-Based vs Outcome-Based Goals
Most goal-setting advice is outcome-based: define the result, work backwards. Identity Over Discipline argues that outcomes make poor engines for behaviour, and that anchoring to identity produces more durable consistency.

The verdict
Outcomes are useful for pointing the way, but they put your identity on hold until the result shows up. That's why a single bad week can derail an outcome-based plan entirely.
The book recommends pairing every outcome with an identity: keep the target for direction, but let a chosen identity drive the day-to-day behaviour.
