NaNos of the world, unite! :D
I always sit down with the goal of "just 100 words". It mostly ends with at least a scene (which tends to be 400-500 words). Then you make a little break, take a sip of your NaNo brew, read a few pages of book and then get back to write just 100 words more.
I also strongly recommend a good (ergonomic) keyboard and - whats the word? I think bandages are slightly wrong - to wrap around your wrists to stabilize them. You dont have 2 or 3 days to make a break to stop the aches in your hands.
