National Novel Writing Month. Write a 50,000 word novel in 30 days. Check out my so-called progress at http://www.nanowrimo.org/eng/user/727997. I would need to produce 1,667 words per day. I skipped November 1 and spent the time developing an interesting premise. I began writing this evening and only managed to churn out 559 words.
I think the key to writing a 50K-word novel in one month is to totally suppress the inner urge to edit as you write. I don't know if I'll be able to do this, sustained, for 30 days. I need to convince myself that this is just a writing exercise--I am not producing my breakout novel!
