How many times have you re-written material for a book? I’m beginning my second draft and reading back parts of the first – it sounds so shitty, it’s making me want to give up.
First drafts are garbage. You should literally throw them away and start from scratch. Second drafts are shit. No one should see them. Third drafts are bad, but you can start showing them to people you trust for critique. Fourth drafts you can send to agents, publishers, and other professionals. Fifth drafts are starting to get good, especially if you’re working with an editor, but they can always get better… you see where I’m going with this.
Writing is rewriting. It never ends, and you can’t give up. You just have to keep hacking away at it. Also, realizing that your first draft is shitty isn’t a bad thing. It’s a gift. It means you know what needs changing, and it means you’re a real writer, because only an amateur thinks the first draft is any good.
