" According to Seneca, “A man is as wretched as he has convinced himself that he is.” He therefore recommends that we “do away with complaint about past sufferings and with all language like this: ‘None has ever been worse off than I. What sufferings, what evils have I endured!’” After all, what point is there in “being unhappy, just because once you were unhappy?”21 "
