I think I may attempt this. I already have a story I'm writing. The main problem with me is actually sitting down and typing. Okay, I have many more problems than that.
Eh. I'm a lazy ******** too, but NaNo made it waaaay easier for me to write. I got 20K in a month - admittedly, that was 10K below what I was looking for, but it was also more than double what I'd ever done before.
I might participate. Summer is going to be crazy for me, as I got accepted into Upward Bound (summer program which helps you prepare for college), and I'll be staying on a college campus every weekday from June 24'th-August 4'th.
Although admittedly, the University of Maine has killer computers in its library. A Summer WriMo would just be one more excuse to spend all my free time in there. And also an excuse to obsessively read No Plot? No Problem! again
