It was enough to have been a unicorn.

“At the end of his life, which had included financial ruin in the Great Depression, his wife's barbiturate addiction and death by overdose, and then his own lung cancer, Doc said, "It was enough to have been a unicorn." What he meant was that he got to do art. It was magic to him that his hands and mind got to make wonderful things, that he didn't have to be just another goat or horse.”
