When I'm editing a story, I have this horrible tendency to move things around rather than fix them. Maybe I write a paragraph on scrap paper during a meeting at work, or I decide some piece of text belongs at the beginning of the story to explain the world (I often move all the boring exposition to the start of the story, for example, in a second or third draft, making the intro nigh unto unreadable). I drop this text into a spot as I move through the document to the end, and then I make another draft, rinse and repeat. And as I progress, each draft doesn't get better. Well, maybe the ending does, but the beginning gets heavier and heavier and that's what people read first so I'm kind of screwing myself. I'm not sure; I have this thing in my head that generally each story starts out not that bad after the first draft, and then through subsequent edits got worse and worse. But that's wishful thinking and the first draft was probably crap and all subsequent drafts...
