Epictetus, Enchiridion 17 tr. Manning
Remember that you are an actor in a play, in whatever kind the producer chooses: if short, then short, if long, then long. If he wants you to play a pauper, or a cripple, or a ruler, or a private citizen, you should play it the best that you can. For this is your job, to play the part that is given to you well, but to chose it belongs to another.
