Fear is the tool of a man-made devil. Self-confident faith in one's self is both the man-made weapon which defeats this devil and the man-made tool which builds a triumphant life. And it is more than that. It is a link to the irresistible forces of the universe which stand behind a man who does not believe in failure and defeat as being anything but temporary experiences.
