Most of you have heard someone say they have a novel idea they'd love to write. Many of you know people who've started and never quite finished. Heck, some of you may have even started a novel yourself that you didn't get around to completing. Any author will tell you, writing a novel and especially committing to finish it, are the hard parts. Ideas are a dime a dozen but sticking with them and caring about them enough to see them through to the finish is priceless. And it's often the difference between a writer and a published author. If you never finish that book there's no way you're going to get it published.
So what makes most people stop and put it aside? One word: Perfectionist. Don't be one. Seriously. As a recovering perfectionist I can say that. You know what we call the first draft? A rough draft. That's not just a catchy phrase, that's how your first draft should look. My first draft is never seen by anyone because I allow it to be rough. Its not meant for criticism or judging eyes, its meant to be a foundation.
Every person I have ever talked to who started a book and didn't finish was editing the heck out of it, and it wasn't done! I never edit before finishing. It makes me second guess myself and can discourage me enough to halt the entire process. For the sake of my book I will not do it. Which is worse, a rough first draft or no first draft?
