I have a pretty developed editing process and I don't like being rushed in it. It's true it's hard to find a lot of the mistakes if you reread right after you finish writing. I've been taught to set the story aside for a while before editing it. I've heard professional writers suggest that. I would normally read over once immediately, then let it marinate. In that time, I come up with ideas and think over what I've written. You lose some of your connection to the piece and can rip it apart later without wanting to cry. Also, you just forget some of what you meant to say, whether that is if that is supposed to be 'there' or 'their' or awkward phrasing, or anything. If it doesn't make sense to you after a month, it really won't make to your reader. But it would make sense to you a day after you wrote it.

I read over my things at least five times, and that's just fics. I've been wallowing over a short story I want to enter into a lucrative contest for closer to a year.
