National Novel Writing Month began Monday, aka NaNoWriMo. If you haven't the wherewithal to pump out a 50,000-word novel in 30 days, perhaps you've got time for this: Wired.com's NaNoWriMi, aka National Novel Writing Minute.
While I know at least a dozen folks taking on the NaNoWriMo challenge this year, this minute thing sounds perfect to me. No prizes, but no stress either. (Full disclosure: I'm a three-time NaNoWriMo came-oh-so-close-but-haven't-ever-finished-er).
Whichever you choose, happy writing!
