You differ from a great man in only one respect: The great man was once a very little man, but he developed one important quality: He recognised the smallness and narrowness of his thoughts and actions. Under the pressure of some task that meant a great deal to him, he learned to see how his smallness, his pettiness endangered his happiness. A great man knows when and in what way he is a little man. A little man does not know he is little and is afraid to know.
