Every Friday I sit down and I start to write my weekly DGLM blog, and after writing and revising, revising some more, and then perhaps one more edit, I'm ready to send it off to Lauren (who'll look over it - sometimes suggest more edits - and then post to the blog). When I read my blog posts, I usually think I could've said something more interesting, or would rather have touched on an issue in a different way, so if it was up to me, I'd be revising my blog entries for hours before I turned in the final version (which is why I never start writing them until late Friday morning - so I'm forced to meet a deadline).
Blog posts are one thing, but thinking about the endless self-editing that goes with book writing exhausts me! If I ever had the guts to sit down and write a novel, I know I'd never be able to hand in a finished manuscript because I'd want to rewrite every page, and then make edits on the edits. Take a look at Jean Hannah Edelstein's Guardian article on the dangers of "overcooking" books, and if you're a compulsive self-editor, you'll relate easily to this one.
So, how many times have you revised your manuscript? And, are you ever really satisfied with the end result?
