Tried it three times, won the first time, failed the other two.
There is no question about it, it is hard work!
But I still remember winning it, it was fantastic =)

Won't do it this year, life being too busy and all.
Still wanting to continue on my map.. but even that is proving to be difficult.


Good luck to anybody trying the effort, it is something you just should do.
My tip is.. don't use a plot you've allready worked on, pick a (random) topic when you start writing. Nanowrimo isn't about quality, it is about quantity. And if you write 50k on the fly, it suddenly becomes a much more pleasant experience as you'll allow yourself to get away with a whole lot more.
PS: it also helps if you remove the backspace and delete buttons from your keyboard =P
