The most important principle of human life is that you become what you think about most of the time. This insight is the foundation of religion, philosophy, metaphysics, psychology, and all success. Your outer world is very much a reflection of your inner world. If you change your thinking, you change your life. Your biggest challenge and your greatest responsibility are to create within yourself the mental equivalent of what you want to experience on the outside. By doing this, you activate all your mental powers and put the forces of the universe to work on your behalf. You take full control over your life. Thousands of people have been asked what they usually think about. Over and over, the most successful men and women report the same things. They think about what they want and how to get it most of the time. Unsuccessful and unhappy people, in contrast, think and talk about what they don't want. They think and talk about their problems and worries, and about the people in their lives that they don't like. But this is not for you. When you think and talk continuously about what you want and how to get it, this way of thinking soon becomes a habit. When you think and talk about what you want, you become more positive, purposeful, and creative. When you stay focused on where you're going, you become a more productive and effective person.
