There's just so much I love about this video. In it Kaufman talks about writing movies, the nature of writers, his "process", his fears, his definitions of success and failure. It's great because you can't help but think about your own work while you're watching it. Messy things like the place of art in advertising and he nature of selling things while connecting with people.
I will note there are a few times the video is a little rough when language barriers present themselves. It's still a great way to spend an hour (if you have one of those to spare).
