I have a great editor and I enjoy, in a masochistic way, being ruthless about my own performance. How do I know, but I think I'm quite good at saying, "That's no good. That's no good. That's it. That's it. That's good." And I'm with the editor who goes, "No, I think you're wrong. That's not your best." There's an initial point in the editing, if you're directing yourself, especially in my case, where you go, "Ouch, ouch, ouch, I can't watch this." And then, there's a point where you become hard-nosed and just take your neurosis away and go, "What's working? That's okay. That's okay. We can lose that, and lose that." You get objective about it.
