'First drafts are for learning what your novel or story is about. Revision is working with that knowledge to enlarge and enhance an idea, to re-form it... Revision is one of the true pleasures of writing.'
Starting a first draft is scary (will it be a good enough story?), but once I get going, I love writing them. There's a thrill to creativity. I enjoy revisions too - the satisfaction that comes from improving, polishing.
