The best day to restart a habit is not January 1. In the research that named the "fresh start effect," the biggest bump on the calendar was the start of a new term, up 47.1 percent, far ahead of a new year at 11.6 percent.
- Landmarks work by filing your slack-off self into a closed chapter, so September, with the timetable snapping back, is a stronger reset than a dark, broke January.
- Framing alone moves people: calling a date "the first day of spring" raised goal sign-ups 354 percent.
- The boost is short-lived. It gets you started, then fades, so you still need a plain system for October.
- The 47.1 percent is students at their own semester, not a promise for everyone, and not medical advice.
