So when we are frustrated, angry or unhappy, never hold anyone except ourselves – that is, our judgements – accountable. - Epictetus

You are a little soul carrying a corpse around, as Epictetus used to say.

And as proof that he has delivered them to you, bring your preconceptions to bear. Bring the arguments of philosophers. Bring what you’ve often heard, and often said yourself; what you’ve read, and what you’ve practised.

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?
