Decision Fatigue

Decision fatigue is the decline in choice quality that builds after a day of many decisions—meals, tasks, notifications, and micro-negotiations with yourself. As the count climbs, you default to the impulsive or easiest option, which is how a strong morning turns into vending-machine dinner and a skipped workout by evening.

The fix is subtraction: pre-decide meals, lay out training clothes, batch notifications, and keep one default breakfast so willpower is reserved for decisions that matter. Watch for the pattern on calendar-heavy days; the problem is volume, not weakness.
