The single highest-leverage habit in this course

If you do only one thing from this entire system, make it the weekly review. Fifteen minutes, same time each week, where you look at your goal and ask three questions.

  1. What progress did I actually make this week? (Be honest, not kind.)
  2. What got in the way? (Pattern or one-off?)
  3. What’s my plan for next week? (Specific actions, on the calendar.)

The weekly review is what separates people who drift from people who adjust. Goals rarely fail in a dramatic moment — they fail through weeks of quiet neglect that nobody notices until it’s too late. The review makes neglect impossible to ignore.

Make it stick

Pick a fixed slot — Sunday evening or Friday afternoon work well — and protect it like an appointment. Keep your notes in one place so you can see trends over the full 90 days.
