Understanding decision fatigue science isn't academic—it's practical. When you know: - Your capacity is limited, you stop blaming yourself for evening lapses - Depletion is physical, you take it seriously - Recovery is possible, you prioritize it - Everyone experiences this, you feel less alone
Most importantly, understanding the science motivates change. You can't willpower your way out of willpower depletion. You need systems, and that's what the rest of this book provides.
