I have interviewed many timid people as to why they let opportunities pass by them that were eagerly seized by others with much less ability, and the answer was invariably a confession like the following:
A physical trainer in one of our girls' colleges says that his first step is to establish the girls in self-confidence; to lead them to think only of the ends to be attained and not of the means. He shows them that the greater power lies behind the muscles, in the mind, and points to the fact so frequently demonstrated, that a person in a supreme crisis, as in a fire or other catastrophe, can exert strength out of all proportion to his muscle. He thus helps them to get rid of fear and timidity, the great handicaps to achievement.
I believe if we had a larger conception of our possibilities, a larger faith in ourselves, we could accomplish infinitely more. And if we only better understood our divinity we would have this larger faith. We are crippled by the old orthodox idea of man's inferiority.
