Motivation gets you started. rewired gets you to day 66.

Most of us don't fail to change because we're lazy — we fail because willpower runs out and we're left guessing what to do next. rewired fixes the “what do I do today” problem. It costs you nothing but commitment to the 66-day program — 66 being roughly how long it actually takes for a new behavior to become automatic — and each day it gives you one small, specific thing. You set what you're working toward, it checks in daily, tracks your streak, and carries you through the rough patches instead of guilt-tripping you with a missed checkmark. It's built on a book that's free to read if you want the science, but you don't need to read anything to start. You just sign up and do today.
