"Changing a habit is like playing a game of chess.In chess there's an early game, a middle game, and an endgame. The same is true for habit change. Many people try to change their habits by skipping straight to the endgame. They dive in and commit themselves to making the change happen right away. This is what people do when they make a New Year's Resolution. It hardly ever works."
