“If you love the good thing vitally, enough to give up for it all that one must give up, then you must hate the cheap thing just as hard. I tell you, there is such a thing as creative hate! A contempt that drives you through fire, makes you risk everything and lose everything, makes you a long sight better than you ever knew you could be.”

Statement quoted in Prophet Singer: The Voice And Vision of Woody Guthrie (2007) by Mark Allan Jackson. There are a few slight variants of this statement, which seems to have originated in a performance monologue.
Context: I hate a song that makes you think that you are not any good. I hate a song that makes you think that you are just born to lose. Bound to lose. No good to nobody. No good for nothing. Because you are too old or too young or too fat or too slim too ugly or too this or too that. Songs that run you down or poke fun at you on account of your bad luck or hard traveling. … I am out to fight those songs to my very last breath of air and my last drop of blood.
I am out to sing songs that will prove to you that this is your world and that if it has hit you pretty hard and knocked you for a dozen loops, no matter what color, what size you are, how you are built, I am out to sing the songs that make you take pride in yourself and in your work.
And the songs that I sing are made up for the most part by all sorts of folks just about like you. I could hire out to the other side, the big money side, and get several dollars every week just to quit singing my own kind of songs and to sing the kind that knock you down still farther and the ones that poke fun at you even more and the ones that make you think you've not any sense at all. But I decided a long time ago that I'd starve to death before I'd sing any such songs as that. The radio waves and your movies and your jukeboxes and your songbooks are already loaded down and running over with such no good songs as that anyhow.

Variant: And now I'm looking at you, he said, and you're asking me if I still want you, as if I could stop loving you. As if I would want to give up the thing that makes me stronger than anything ever has.

Paris Review interview (1958)
Context: From things that have happened and from things as they exist and from all things that you know and all those you cannot know, you make something through your invention that is not a representation but a whole new thing truer than anything true and alive, and you make it alive, and if you make it well enough, you give it immortality. That is why you write and for no other reason that you know of. But what about all the reasons that no one knows?
