Say to yourself in the early morning: I shall meet today ungrateful, violent, treacherous, envious, uncharitable men. All of these things have come upon them through ignorance of real good and ill... I can neither be harmed by any of them, for no man will involve me in wrong, nor can I be angry with my kinsman or hate him; for we have come into the world to work together.

There is but one thing of real value - to cultivate truth and justice, and to live without anger in the midst of lying and unjust men.

It never ceases to amaze me: we all love ourselves more than other people, but care more about their opinions than our own.

The happiness of your life depends upon the quality of your thoughts: therefore, guard accordingly, and take care that you entertain no notions unsuitable to virtue and reasonable nature.

The main thing we were made for is to work with others.

When you are offended at anyone's fault, turn to yourself and study your own failings. By attending to them, you will forget your anger and learn to live wisely.

Enough of this wretched life and murmuring and apish tricks. Why art thou disturbed? What is there new in this? What unsettles thee? Is it the form of the thing? Look at it. Or is it the matter? Look at it. But besides these there is nothing. Towards the gods, then, now become at last more simple and better. It is the same whether we examine these things for a hundred years or three.
