But, beginnings are HARD! I forgot how daunting a blank Word doc feels, since I've been revising COTF for so long. It's ominous and so open-ended. I'm not far in and I'm already second guessing myself. Did I put in enough world building? Are my characters coming to life? Do they have the right personality?
But you know what? That doesn't matter. I mean it matters, but that's not what the first draft is about. It's about getting the story on the page. Second and third and fourth (etc) drafts are for polishing. First drafts are supposed to be crappy. This is something I have to continually remember, so that I don't get hung up on word choice. If my character sighs three times on a page, it doesn't matter; that's what revisions are for. Just GET IT DOWN on the page. Don't stop. Don't revise. Just go go go!
I've read so many author blog posts about giving permission to write crap and to fail. It's something I believe in too. If we're so concerned with the first draft being good, we will probably never finish it. My revisions are MASSIVE but that's okay. At least I finished. So don't worry so much with if the first draft is good, or if you're following your outline exactly. Get it down and change it later. Whatever helps you finish the draft is what you should do.
