When you are offended at any man's fault, turn to yourself and study your own failings. Then you will forget your anger. - Epictetus

If someone is the street were entrusted with your body, you would be furious. Yet you entrust your mind to anyone around who happens to insult you, and allow it to be troubled and confused. Aren't you ashamed of that?

Attach yourself to what is spiritually superior, regardless of what other people think or do. Hold to your true aspirations no matter what is going on around you.

If you want to improve, be content to be thought foolish and stupid with regard to external things. Don't wish to be thought to know anything; and even if you appear to be somebody important to others, distrust yourself.
