After the publication of Tender Is The Night, Fitzgerald asked Hemingway what he thought of the novel. Hemingway’s entire letter is a must-read, but if anything, get into this excerpt:
Forget your personal tragedy. We are all bitched from the start and you especially have to hurt like hell before you can write seriously. But when you get the damned hurt use it—don’t cheat with it. Be as faithful to it as a scientist—but don’t think anything is of any importance because it happens to you or anyone belonging to you.
About this time I wouldn’t blame you if you gave me a burst. Jesus it’s marvellous to tell other people how to write, live, die etc.
