“I shall make whatever befalls me become a good thing, but I prefer that what befalls me should be comfortable and pleasant and unlikely to cause me annoyance: for you need not suppose that any virtue exists without labour, but some virtues need spurs, while others need the curb. As we have to check our body on a downward path, and to urge it to climb a steep one; so also the path of some virtues leads downhill, that of others uphill. Can we doubt that patience, courage, constancy, and all the other virtues which have to meet strong opposition, and to trample Fortune under their feet, are climbing, struggling, winning their way up a steep ascent? Why! is it not equally evident that generosity, moderation, and gentleness glide easily downhill? With the latter we must hold in our spirit, lest it run away with us: with the former we must urge and spur it on.”
—Seneca the Younger.
