From Paris Review via the LA Times

"No, no, no. I think nobody on earth writes down. Garbage though they turn out, Hollywood writers aren’t writing down. That is their best. If you’re going to write, don’t pretend to write down. It’s going to be the best you can do, and it’s the fact that it’s the best you can do that kills you. I want so much to write well, though I know I don’t, and that I didn’t make it. But during and at the end of my life, I will adore those who have." -Dorothy Parker
