As far as possible the duty of a leader is to foresee dissatisfaction and to remedy injustice before complaints are made. To accomplish this he must maintain close contact with the men he controls.

He must have some imagination; an understanding of other men's lives is necessary to him, so that he may be able to protect those under him from unnecessary suffering. The secret of gaining their affection is to feel affection for them and to be able to do their jobs as well as they do them themselves. Men endure taking orders, and even like it, if the orders are given intelligently.
