Don't get seduced by your own stuff. Don't get high on your own supply. The hardest thing as a filmmaker is when you're watching a film that you've worked on for several years. You know every frame so intimately that holding lots of the objectivity of a new viewer who has just seen it for the first time is the hardest thing. Every aesthetic decision you make - and you make thousands of them every day, have to - in theory, must be done from you being a blank slate. You almost have to run a program, like a mind wipe, every time you watch the movie.
