If you have a success, you have it for the wrong reasons. If you become popular it is always because of the worst aspects of your work.

Don't get discouraged because there's a lot of mechanical work to writing. I rewrote the first part of Farewell to Arms at least fifty times.

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.

Now a writer can make himself a nice career while he is alive by espousing a political cause, working for it, making a profession of believing in it, and if it wins he will be very well placed. All politics is a matter of working hard without reward, or with a living wage for a time, in the hope of booty later. A man can be a Fascist or a Communist and if his outfit gets in he can get to be an ambassador or have a million copies of his books printed by the Government or any of the other rewards the boys dream about.

Try to learn to breathe deeply, really to taste food when you eat, and when you sleep, really to sleep. Try as much as possible to be wholly alive with all your might, and when you laugh, laugh like hell. And when you get angry, get good and angry. Try to be alive. You will be dead soon enough.

I mistrust all frank and simple people, especially when their stories hold together

So this was how you died, in whispers that you did not hear.
