I try to write everyday. I do that much better over here than when I'm teaching. I always rewrite, usually fairly close-on which is to say first draft, then put it aside for 24 hours then more drafts.
The problem is you tend to look back and identify mistakes, and as a consequence of feeling terrible about mistakes you say you bungled this so bad, let's get out of here.
If everything always went perfectly, I would feel like, When is the ball going to drop? Because good things don't always last. Maybe I'm a pessimistic person. When something just seems too good, I can't believe it.
