Hemingway on playwriting, in a rediscovered letter:

“The making part of a play comes after the writing of it. Other people do all the great detail that you just indicate when you write. Right now I have been working steadily for a year and a month on a novel. In that no one can help you. But in a play the credit for all the really hard work goes to those who stage, direct, and act in it. I had all the fun. They had all the work. Well, that is a nice kind of an exchange for once.”
