NaNoWriMo.
This is something like the 12th time I've participated, and this will be the third time I've attended the fundraiser/word frenzy known as Night of Writing Dangerously, the second time I'll finish at said event.
Since I've got about 20,000 words to write in the next two days, and another 5,000 on the third day, NANOWRIMO IS MY LIFE RIGHT NOW.
