Believe in yourself! Have faith in your abilities! Without a humble but reasonable confidence in your own powers you cannot be successful or happy.... Formulate and stamp indelibly on your mind a mental picture of yourself as succeeding. Hold this picture tenaciously. Never permit it to fade. Your mind will seek to develop the picture ... Do not build obstacles in your imagination ... Do not be awestruck by other people and try to copy them. Nobody can be you as efficiently as you can.

~ Norman Vincent Peale 1898
