Ever feel mentally drained by midday, even before tackling your hardest work? You might be experiencing decision fatigue—the gradual depletion of mental energy from making too many choices, big or small. Every outfit you pick, every app notification you answer, every trivial work task… they chip away at your cognitive bandwidth.
Decision fatigue is the scientifically proven phenomenon where the quality of your decisions deteriorates after a prolonged session of decision-making. Studies show that judges are less lenient later in the day, shoppers overspend after endless product comparisons, and even simple personal tasks feel overwhelming by evening.
You have a limited reservoir of willpower and mental clarity each day. Treat it like a precious resource. Simplifying your routines, eliminating trivial choices, and structuring your day intentionally can dramatically boost focus, reduce burnout, and help you make smarter decisions when they matter most.
