Believe in Yourself by Joseph Murphy

The first step toward your goal is the birth of the idea in the mind, and the second step is the manifestation of the idea. Imagine yourself doing the thing you long to do, and possessing the things you long to possess. Become imaginative; mentally participate in the reality of the successful state; enter into that state of consciousness frequently; make a habit of it; then you will find you will be guided to do everything necessary for the realization of your dream. Go to sleep feeling successful every night and perfectly satisfied. You will succeed eventually in implanting the idea of success in your subconscious mind.
