Interviewer: How much rewriting do you do?
Hemingway: It depends. I rewrote the ending of Farewell to Arms, the last page of it, 39 times before I was satisfied.
Interviewer: Was there some technical problem there? What was it that had stumped you?
Hemingway: Getting the words right.
(Ernest Hemingway, “The Art of Fiction,” The Paris Review Interview, 1956)
