This'll be my third Nanowrimo. I'm both excited and worried, since I'm much busier than I was with the last two. It requires a lot of dedication and focus, but if you just keep writing no matter what you should be able to pull it off if you don't get hit by a truck of writer's block. For me whole thing became a lot easier once I created a chapter outline, which I unfortunately didn't have time to do this time around.
