When I see an anxious man, I say, “What does this man want?” If he did not want something which is not in his power, how could he be anxious? For this reason, a lute player when he is singing by himself has no anxiety, but when he goes to the theatre, he is anxious, even if he has a good voice and plays well on the lute, for he not only wishes to sing well, but also to obtain applause, which is not in his power.
