Inhale, and I want you to exhale, and I want you to follow your breath. Inhale, and I want you to exhale, and I want you to follow your breath. Let me tell you something which, if you really understand it, will alter your life immediately. If you understand completely what I'm going to tell you from this moment on, your life will never be the same again. Doubt, fear, well, they'll be things of the past. Doubt is the key to success, and the key to failure. We become what we think about. The greatest discovery of my generation is that human beings can alter their lives by altering their attitudes of mind. We need only in cold blood act, as if the thing in question was real, then it will become real.
