David Schwartz in The Magic of Thinking Big lists 7 steps to grow the action habit.
1. Don't wait for the perfect condition. There never be a perfect condition. Take the plunge and solve problems as they arise.
3. Take action and cure fear. Just do it and watch your fear disappear.
4. Start your mental engine mechanically. Move your spirit, dig in and take action.
5. Live in the present. Develop the now mentality.
6. Get down to business. Don't just get ready to act. Act.
7. Take the initiative. Pick the ball and run. Go and slam dunk it.
