Compete with your previous habits.

Your existing habits are the real opposition, and they are formidable because they are automatic, comfortable, and supported by your entire environment. Any change has to beat them, not in theory but in practice, on ordinary days when nothing feels urgent.

Name the one habit that most reliably costs you what you want. Do not try to eliminate it. Compete with it: give it one fewer opportunity each day and see how much ground you take back.
