Personal Development for Smart People, by Steve Pavlina, is a book that helps you master personal development. You do so by learning the seven timeless principles of personal development that apply to all aspects of your life.
Bruce Lee believed that as you learn something, you move through three stages towards mastery. And when you are a master, you rise above the technique. You rise above the form. It becomes artless and fluid and your own personal expression.
You can live and operate at a higher level. There are three levels of living: Level 1, living your moments, Level 2, living your values, Level 3, living your contribution.
