“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 actions. The things in our control are by nature free, unrestrained, unhindered; but those not in our control are weak, slavish, restrained, belonging to others. Remember, then, that if you suppose that things which are slavish by nature are also free, and that what belongs to others is your own, then you will be hindered. You will lament, you will be disturbed, and you will find fault both with gods and men. But if you suppose that only to be your own which is your own, and what belongs to others such as it really is, then no one will ever compel you or restrain you. Further, you will find fault with no one or accuse no one. You will do nothing against your will. No one will hurt you, you will have no enemies, and you not be harmed.”
― Epictetus, Enchiridion and Selections from the Discourses

“If anyone tells you that a certain person speaks ill of you, do not make excuses about what is said of you but answer, "He was ignorant of my other faults, else he would not have mentioned these alone.”
― Epictetus

“Any person capable of angering you becomes your master;
he can anger you only when you permit yourself to be disturbed by him.”
― Epictetus

“You have no responsibility to live up to what other people think you ought to accomplish. I have no responsibility to be like they expect me to be. It's their mistake, not my failing.”
