“There isn’t always an absolute right way and a wrong way to do things, but there usually is a better way, a high-percentage way. The positive thinker generally feels that his way will be the right way and nothing will go wrong, if he just believes. The negative thinker disbelieves. He takes every precaution to prevent the wrong thing from happening, and in doing so has a much better chance of things turning out right in the end.”
