Definitely not, but also absolutely yes. It's a weird, desperate, running-around-like-a-beheaded-chicken sort of feeling. I decided to join in this year because I have a character or two and an entire universe and mythology sitting patiently in my brain... and absolutely no idea at all where the plot should go. But I already love the story very much. I don't think I'll be ready to try NaNo with it this year (though I may use NaNo to finish an old project that's stalled in the middle!), but I am really excited to see what the excellent structure and great resources over here will drag out of my disaster brain this October!
