Definition
A Daily Performance Journal is a repeatable end-of-day log: what you ran, what you avoided, and one honest score — not a diary of mood. It closes the Morning Journal rail and feeds weekly review.
Origin
Athletes, traders, and executives have long used structured performance logs. Locke and Latham’s goal-setting synthesis shows specific, challenging goals plus feedback improve task performance — a minimal journal supplies that feedback loop at day scale.
Mechanism
Minimum viable loop:
- One lead you controlled today.
- One lag you read (optional same day).
- One sentence of friction or victory.
Overload kills the journal; shorter capture rituals often absorb the load. Sonnentag and Fritz’s detachment model adds that psychological detachment from work during off-hours predicts recovery — a performance log should close the day, not extend rumination (modest contrasting tally on boundary conditions).
Applications
Point to Victory Journal when the need is stack-based wins; to Morning Voice when the need is voice-first capture; to Morning Journal when the need is morning question rails. A 60-second template is the viability threshold — longer forms decay. Open via iPhone Shortcuts so friction cannot kill the close.
