These are all Ernest Hemingway quotes.(including my comments)

Never go on trips with anyone you do not love.

That is what we are supposed to do when we are at our best - make it all up - but make it up so truly that later it will happen that way.

That terrible mood of depression of whether it's any good or not is what is known as The Artist's Reward.

The only thing that could spoil a day was people. People were always the limiters of happiness except for the very few that were as good as spring itself.

(This quote just makes me want to be as good as spring itself!)

The shortest answer is doing the thing.

(I feel this is a good tip for me, a procrastinator.)

 The world is a fine place and worth the fighting for and I hate very much to leave it.

There are events which are so great that if a writer has participated in them his obligation is to write truly rather than assume the presumption of altering them with invention.
(thank you!)

There is nothing to writing. All you do is sit down at a typewriter and bleed.
(yes!)

When I have an idea, I turn down the flame, as if it were a little alcohol stove, as low as it will go. Then it explodes and that is my idea.

When writing a novel a writer should create living people; people not characters. A character is a caricature.

Writing and travel broaden your ass if not your mind and I like to write standing up.

You can wipe out your opponents. But if you do it unjustly you become eligible for being wiped out yourself.

You're beautiful, like a May fly.
