I know everyone has a different writing method that works best for them. I often hear people recommend turning off the internal editor and getting out the words as fast as you can. First drafts are supposed to be terrible. That's what revising is for, right? Well, that sounds good, but it doesn't work for me. At all. That's one reason I won't participate in Nanowrimo. I just don't see the point in spewing out a bunch of bad writing. It feels like a waste of time to me. Isn't it better to get right the first time? Close to right, anyway? I still have to do revising, of course.
I've noticed while typing up my novella that the pages I wrote faster than normal in October are, well, in need of more editing than usual. That annoys me. It's not terrible, but it's not quite as good as usual. So, I'm keeping my internal editor turned on. I edit as I go, and I like that! (I am an editor too after all.) Sure I write slower than some. First drafts don't come pouring out of me in a flood. But I bet if we all added up the time it takes to get to a polished manuscript, it probably comes out the same.
The internal critic, though? That's another matter entirely!
