Why 500 Days? The Psychology of Long-Term Planning
Five hundred days represents a “sweet spot” in human psychology—it’s long enough to achieve significant goals (learn a language, train for a marathon, launch a startup) but short enough to maintain urgency and focus. Research from the University of Scranton shows that 92% of people fail their New Year’s resolutions because they lack concrete mid-term milestones. A 500-day framework provides a tangible anchor point between short-term tasks and decade-long visions.
