You can fool me, but you cannot fool Ernest Hemingway!
Ernest Hemingway: I hate it.
Gil: You haven't even read it yet.
Ernest Hemingway: If it's bad, I'll hate it. If it's good, then I'll be envious and hate it even more. You don't want the opinion of another writer.
The artist's job is not to succumb to despair but to find an antidote for the emptiness of existence.
