Formulate and stamp indelibly on your mind a mental picture of yourself succeeding. Hold this picture tenaciously. Never permit it to fade. Do not be awestruck by other people and try to copy them. Nobody can be you as efficiently as YOU can. Remember also that most people, despite their confident appearance and demeanor, are often as scared as you are and as doubtful of themselves.
Norman Vincent Peale, The Power of Positive Thinking
