I thought about it last year but then didn't go for it because I just knew I wouldn't have enough time, even though -- back then -- I was still good at producing humungous word counts in a rather short time. Sine then however, I've learned to be very wary of when this happens, because mostly the result is just crap. Also, while a bit of pressure is good to get me writing when I'm tired or would waste time surfing around because I don't want to force myself to concentrate, it's not good when it gets me writing when I just don't feel like it at all. For me, sometimes trying to write when it just doesn't want to flow is worse than not writing at all. Did this make any sense? Then again, you asked for my thoughts ;-)
