Charles Baudouin said this quote

To be ambitious for wealth and yet always expecting to be poor to be always doubting your ability to get what you long for is like trying to reach east by traveling west. There is no philosophy which will help a man to succeed when he is always doubting his ability to do so and thus attracting failure. No matter how hard you work for success if your thought is saturated with the fear of failure it will kill your efforts neutralize your endeavors and make success impossible.

~ Charles Baudouin
