If you now neglect things and are lazy and are always making delay after delay and set one day after another as the day for paying attention to yourself, then without realizing it you will make no progress but will end up a non-philosopher all through life and death. So decide now that you are worthy of living as a full-grown man who is making progress, and make everything that seems best to be a law that you cannot go against. And if you meet with any hardship or anything pleasant or reputable or disreputable, then remember that the contest is now . . . and you cannot put things off anymore and that your progress is made or destroyed by a single day and a single action.
Now there are two kinds of hardening, one of the understanding, the other of the sense of shame, when a man is resolved not to assent to what is manifest nor to desist from contradictions. Most of us are afraid of mortification of the body, and would contrive all means to avoid such a thing, but we care not about the soul's mortification. And indeed with regard to the soul, if a man be in such a state as not to apprehend anything, or understand at all, we think that he is in a bad condition; but if the sense of shame and modesty are deadened, this we call even power (or strength).
Δείξατέ μοί τινα νοσοῦντα καὶ εὐτυχοῦντα, κινδυνεύοντα καὶ εὐτυχοῦντα, ἀποθνῄσκοντα καὶ εὐτυχοῦντα, πεφυγαδευμένον καὶ εὐτυχοῦντα, ἀδοξοῦντα καὶ εὐτυχοῦντα.From Epictetus's discourse against those who take up the philosophers' teachings only to talk about them (Discourses II.19), recorded by his student Arrian.
Small-minded people habitually reproach others for their own misfortunes. Average people reproach themselves. Those who are dedicated to a life of wisdom understand that the impulse to blame something or someone is foolishness, that there is nothing to be gained in blaming, whether it be others or oneself.
