"It begins with the natural feeling that one wants to serve, to serve first. Then conscious choice brings one to aspire to lead. That person is sharply different from one who is leader first, perhaps because of the need to assuage an unusual power drive or to acquire material possessions...The leader-first and the servant-first are two extreme types. Between them there are shadings and blends that are part of the infinite variety of human nature."
