Oh! Realization about myself at 20K

Yay, I got to the 20K!
It's spread over 6 stories, but that's fine - I feel good with those six at the moment, so perhaps I can hit the midway point without starting another story.

20K is more than I have written during the whole year - and I did it in 12 days (and I'm not done yet!).

I've been saying to myself for a long time that 'I can't write, I'm blocked'. Well, that's obviously bullshit - I can write, since I just did it? So the truth is more like: 'I don't want to write, and writer's block is a convenient excuse for it'

The core question: so why don't I want to write?
I suppose if I can figure out the answer to that, I could feel better writing even outside NaNo (gasp!)

Next stop: 25K Midway Point!
