[Epictetus] used to say that there were two faults which were by far the worst and most disgusting of all, lack of endurance and lack of self-restraint, when we cannot put up with or bear the wrongs which we ought to endure, or cannot restrain ourselves from actions or pleasures from which we ought to refrain. “Therefore,” he said, “if anyone would take these two words to heart and use them for his own guidance and regulation, he will be almost without sin and will lead a very peaceful life. These two words,” he said, “are ἀνέχου (persist) and ἀπέχου (resist).”
