Fear

Fear is the reason that people fail to excel. Fear is to be overwhelmed by doubt that you cannot be good enough. As Franklin Delano Roosevelt said: "There's nothing to fear but fear itself." Fear is the only thing that stops people from achieving their potential for greatness, and it convinces men that they are not what they are meant to become. All men and women deserve excellence, but fear persuades men to think that only some people are good enough to change the world.
