When you start to live outside yourself, it's all dangerous.

To invent out of knowledge means to produce inventions that are true. Every man should have a built-in automatic crap detector operating inside him. It also should have a manual drill and a crank handle in case the machine breaks down. If you're going to write, you have to find out what's bad for you. Part of that you learn fast, and then you learn what's good for you.

When I had finished the book I knew that no matter what Scott did, nor how he behaved, I must know it was like a sickness and be of any help I could to him and try to be a good friend. He had many good, good friends, more than anyone I knew. But I enlisted as one more, whether I could be of any use to him or not. If he could write a book as fine as The Great Gatsby I was sure that he could write an even better one. I did not know Zelda yet, and so I did not know the terrible odds that were against him. But we were to find them out soon enough.

Never confuse motions with action.

I started out very quiet and I beat Mr. Turgenev. Then I trained hard and I beat Mr. de Maupassant. I've fought two draws with Mr. Stendhal, and I think I had an edge in the last one. But nobody's going to get me in any ring with Mr. Tolstoy unless I'm crazy or I keep getting better.

There is no hunting like the hunting of man, and those who have hunted armed men long enough and liked it, never care for anything else thereafter.

I always try to write on the principle of the iceberg. There is seven-eighths of it underwater for every part that shows.
