George Lucas talking about biggest lesson he learned from Coppola

"Look, when you write a script, just go as fast as you can. Just get it done. Don't ever read what you've written. Try to get it done in a week or two, then go back and fix it, and then go back through as fast as you can, and then go back and fix it – you just keep fixing it. But if you try to make each page perfect, you'll never get beyond page 10."
