On answering a question about “how” he writes, whether with an outline or notes, Ernest Hemingway stated:
No, I just start it. Fiction is inventing out of what knowledge you have. If you invent successfully, it is more true than if you try to remember it. A big lie is more plausible than truth. People who write fiction, if they had not taken it up, might have become very successful liars.
