So for my first novel, so afraid was I of not finishing, that I was mainly concerned with hitting a word count every day just so I could get everything on paper before my quitter-face came on. It worked. I banged out a novel. Not a really great one, but I finished, which was a big milestone. I even rewrote the whole thing from scratch - another 70k words - finished the second draft too. My second novel was during NaNo, so obviously I had to hit a word count every day. It's not good. Writing fast gets it completed, but "completed" is pretty much the only thing you can say about it.
For The Forever City, I've been writing excruciatingly slowly. Because I don't have a word count goal every day, and I edit as I go, which means deleting 500-1,000 words at a time when I feel like a scene is badly written or doesn't need to be there. This is not supposed to be the way you do first drafts, but this is the way it's happening for this one. I can't decide if this is going to be better or worse. We will see.
On another note, I'm turning twenty on Friday, which makes me not a teenager. In three days, I officially will have beaten teen pregnancy. WIN. Major accomplishment.
*ALSO, I realized that since I have a MacBook, my keyboard doesn't actually have a "backspace" key. Haha, picturefail.
