I have a habit that might be good or might be bad.
When I'm writing a rough draft, I tend to read it through from the beginning - every time.
So after a while, I've read those first few chapters a lot more times than the last few chapters.
I read an article about revision somewhere that called this "the house that Jack built" method of revision.
Is that good or bad?
I'm not sure - but that's the way I like to do it. I need to get back in the total flow of the story, and sometimes (usually) that requires starting from the beginning again.
One thing I do know: those first chapters are pretty darned polished!
As for the last chapters? Well, maybe...not so much.
...that tossed the dog,
that worried the cat,
that killed the rat,
that ate the malt
that lay in the house that Jack built.
