*takes some of the mightily well-preserved oranges*
I'm not quite full time at my (rather less than interesting) job. I made it to 50,506 (including titles) on Thursday night, but haven't had time to post since (busy fun weekend followed by hellacious storm, etc.).
Mary, the whole point of NaNo is that quality doesn't matter zilch. As long as it's there, and long, that's perfectly alright. Which means cumbersome circumlocutions and redundancy are almost encouraged.
As well as long asides, musings on things only tangibly related to the main plot. There kind of gets to be an art about it. At this point last year I wrote 1k words an hour, now it's more like 1500-2000 words an hour, so the time involved isn't that terrible, about an hour a night.
Of course, this only gets you as far as a large, meandering first draft. I'm still learning the basics of revision, which is a new problem for me (and more time consuming). It's a method that doesn't work for everyone (but has for me, as it's helped me bust through road blocks in my mind, and forced me (through need of more words) to explore metaphor rather than racing through the plot without any asides).
