I'm with you on editing being a pain sometimes. Fixing little things like grammar or syntax can feel cleansing sometimes-- like "I'm glad my writing has improved since I wrote this," or even just "Now that looks a lot better," but cutting things can be hard.

The worst is when you really like the scene and there's nothing really wrong with it, except that it slows the story down unnecessarily, doesn't fit in with the POV, isn't really relevant, etc. It's that whole "kill your babies" thing... very sad.
