Book excerpt: Nobody and nothing in the world has the power to make you happy or unhappy. It's only you who can do that. Or rather it is the self-talk that goes on within your mind that makes you feel the way you do. And that's not all. It's you who creates your world through your self-talk. Prosperity or poverty, success or failure, happiness or sadness, health or disease, good relations or bad are all a result of your belief system. To turn your beliefs into positive and beneficial ones, you need to consciously change your self-talk. Your self-talk makes or breaks your world; then why not use it to create the best things for you? This is exactly what this book teaches you in a very interesting way. Let the magic of self-talk work in your life to make it a supreme life as well as to make your world beautiful.
