Here's a quote that seemed just what I think about the process at the moment:
Writing is about hypnotizing yourself into believing in yourself, getting some work done, then unhypnotizing yourself and going over the material coldly. There will be many mistakes, many things to take out and other that need to be added. You just aren't always going to make the right decision.
That pretty much sums it up for me. Right now, I'm desperately trying to stay hypnotized and avoid breaking the spell. Sometimes I feel a little out of it, I have to confess, because my subconscious is whirring away trying to figure out what the hell is coming next in each scene. A fine cold eye is definitely not what I need right now.
