Marcus Aurelius
Meditations 8.10
Repentance is a kind of self-reproof for having neglected something useful; but that which is good must be something useful, and the perfect good man should look after it. But no such man would ever repent of having refused any sensual pleasure. Pleasure then is neither good nor useful.
Marcus Aurelius, Meditations 8.10, translated by George Long
Repentance is a sort of self-reproach at some useful thing passed by; but the good must needs be a useful thing, and ever to be cultivated by the true good man; but the true good man would never regret having passed a pleasure by. Pleasure therefore is neither a useful thing nor a good.
Marcus Aurelius, Meditations 8.10, translated by C. R. Haines
