People are not disturbed by things, but by the view they take of them.

Never depend on the admiration of others for self-satisfaction. It is a fact of life that other people, even people who love you, will not necessarily agree with your ideas, understand you always, or share your enthusiasms.

Who are those people by whom you wish to be admired? Are they not these whom you are in the habit of saying that they are mad? What then? Do you wish to be admired by the mad?

If you desire to be good, begin by believing that you are wicked.

If any be unhappy, let him remember that he is unhappy by reason of himself alone. For God hath made all men to enjoy felicity and constancy of good.

Keep silence for the most part, and speak only when you must, and then briefly.

Don't demand or expect that events happen as you would wish them do. Accept events as they actually happen. That way, peace is possible.
