When a man is proud because he can understand and explain the writings of Chrysippus, say to yourself, 'if Chrysippus had not written obscurely, this man would have had nothing to be proud of.'

These are the signs of a wise man: to reprove nobody, to praise nobody, to blame nobody, nor even to speak of himself or his own merits.

No man is free who is not master of himself.

Do not try to seem wise to others.

You can be invincible, if you enter into no contest in which it is not in your power to conquer.

Some things are in our control and others not. Things in our control are opinion, pursuit, desire, aversion, and, in a word, whatever are our own actions. Things not in our control are body, property, reputation, command, and, in one word, whatever are not our own actions.

Freedom is the only worthy goal in life. It is won by disregarding things that lie beyond our control. Stop aspiring to be anyone other than your own best self: for that does fall within your control.
