Today is the start of National Novel Writing Month, which I did two years ago and managed to hammer out the first draft of the novel I still haven't finished yet. I'm not doing NANO this year, because there's a huge chunk taken out of my November by a CRUISE TO THE CARIBBEAN (YEEEE!!!!) and I really do need to finish Shooter Vanished (and maybe the other two novels moldering on my hard drive) before I start a new project. Anyway, the above article has some good points about the mental benefits of writing regularly.
