That terrible mood of depression of whether it's any good or not is what is known as The Artist's Reward.
Ernest HemingwayHow little we know of what there is to know. I wish that I were going to live a long time instead of going to die today because I have learned much about life in these four days; more, I think than in all other time. I'd like to be an old man to really know. I wonder if you keep on learning or if there is only a certain amount each man can understand. I thought I knew so many things that I know nothing of. I wish there was more time.
