Abstract
Baumeister and colleagues propose ego depletion — the active self draws on a limited resource that fatigues after repeated self-control acts, lowering performance on unrelated tasks.

Key findings
- Limited resource — Self-control behaves like a depletable strength — not infinite will.
- Cross-task bleed — One act of control weakens the next unrelated demand.
- Active self — The executive self that overrides impulse is what tires.
- Recovery matters — Rest and glucose hints suggest restoration — plan breaks, not endless push.
Limits
Ego depletion model — influential but contested; replication and boundary conditions evolved after this paper.
Application
When the day feels like one willpower tank — repeated acts may deplete self-control resources in this model; plan recovery, not endless push. See Phagocytise energy.
