Editing is basically the undesirable step-child of writing; ugly, uncouth, a little more violent than you’d like, and rarely discussed in polite company. When you write, you have to love your ideas, but when you edit, you can’t love everything or you won’t be able to brush away the clutter to reveal a landscape of clear, strong thoughts.
I am revising my screenplay right now. To do it well, I have to be able to read a scene and say things to myself like “Nothing interesting happens in this scene. Whoever wrote this scene was a very boring person. Good thing I’m here to clean up the mess.” I couldn’t be that honest if my ego were sitting in my lap, sobbing and choking out the phrase “I THOUGHT WE WERE SPECIAL.”
