"You only have control over three things in your life--the thoughts you think, the images you visualize, and the actions you take (your behavior).

How you use these three things determines everything you experience. If you don't like what you are producing and experiencing, you have to change your responses. Change your negative thoughts to positive ones. Change what you daydream about. Change your habits. Change what you read. Change your friends. Change how you talk."
