Do not criticize, do not condemn or complain: God does not intend to judge man until the end of his days. Why, then, should you or I judge him?
Show honest and sincere appreciation: The difference between appreciation and flattery is very simple. One is sincere and the other is not. One arouses universal admiration; the other is universally punished.
Arouse in others a burning desire: If there is a secret of success, it lies in the ability to appreciate the other's point of view and to see things from that point of view as well as your own.
