I write first drafts feverishly fast, and then I spend years editing. It's not that sentence-by-sentence perfectionist technique some writers I admire use. I need to see the thing, in some form, and then work with it over and over and over until it makes sense to me - until its concerns approach me, until its themes come to my attention. At that editing stage, the story picks itself and it's just up to me to see it, to find it. If I've done a good job, what it all means will force me to confront it in further edits.
