In 5.5 hours this afternoon I wrote more than I have all day for the last week!
So, I've decided not to even open up Word until at least 11am every day... if I start the laptop before that, it's purely for checking my email and forums and things like that.
Then the closest I'm allowed to writing is reading through the previous chapter at 10.50am ready for the words to flow at 11am.
If that works every day next week I'll be back into my writing mindframe ready for NaNo again! Yay!
