I gotta say, that's one thing that NaNo did for me. No editing while first-drafting. It was part of the whole experience, and I gave it a try though it was definitely NOT the way I normally write. Normally, I edit as I go and things take forever while I get just the right phrase, just the right words, just the right 'feel'.
It was one of the main reasons I donated to NaNo last year. I couldn't really afford it, but it was a powerful lesson to learn, finding out I could do it. And now here I am with my first novel-length piece of fiction. Coincidence maybe, but... Maybe not.
Also, I'll hafta get used to calling it a "line edit". It's the standard term, the industry one, but I've always called it a "finesse edit".
