In order to be a leader a man must have followers. And to have followers, a man must have their confidence. Hence, the supreme quality for a leader is unquestionably integrity. Without it, no real success is possible, no matter whether it is on a section gang, a football field, in an army, or in an office. If a man's associates find him guilty of being phony, if they find that he lacks forthright integrity, he will fail. His teachings and actions must square with each other. The first great need, therefore is integrity and high purpose.
