The first draft reveals the art, revision reveals the artist.
Revision is one of the exquisite pleasures of writing.
In working on a poem,I love to revise. Lots of younger poets don't enjoy this, but in the process of revision I discover things.
There's different styles of writing, and then there's rewriting. For me, it comes from the heart first, from what I feel needs to be said, and from there I can shape it based on the reality that I live in.
Rewriting to me means, if I work on it for three days, I've rewritten it.
Rewriting is a large part of the whole job. And get rid of stuff that's not working. Just pare it down until it's a beautiful thing you can hand in, probably late, to your editor.
The process of rewriting is enjoyable, because you're not in that existential panic when you don't have a novel at all.
If it sounds like writing, I rewrite it.
