When you desire something outside your sphere of power, you set yourself up for disappointment - Epictetus

You ought to realize, you take up very little space in the world as a whole — your body, that is; in reason, however, you yield to no one, not even to the gods, because reason is not measured in size but sense. So why not care for that side of you, where you and the gods are equals?

Two elements are combined in our creation, the body, which we have in common with the beasts; and reason and good judgement, which we share with the gods. Most of us tend toward the former connection, miserable and mortal though it is, whereas only a few favour this holy and blessed alliance.

"At first, keep quiet and count the days when you were not angry: "I used to be angry every day, then every other day: next every two, next every three days!" and if you succeed in passing thirty days, sacrifice to the Gods in thanksgiving."
