Ask yourself, "How are my thoughts, words and deeds affecting my friends, my spouse, my neighbour, my child, my employer, my subordinates, my fellow citizens?"

If you see anybody wail and complain, call him a slave, though he be clad in purple.

No man is free who is not master of himself.

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.

On the occasion of every accident that befalls you, remember to turn to yourself and inquire what power you have for turning it to use.

There is only one way to happiness and that is to cease worrying about things which are beyond the power of our will.
