“If you would attract good fortune, you must get rid of doubt. As long as that stands between you and your ambition, it will be a bar that will cut you off. You must have faith. No man can make a fortune while he is convinced that he can't.”

He founded *Self-Culture*, a magazine promoting personal development and success principles, and became a leading voice in the self-help movement of his era.
