I regularly hit 1000 words a day target by 2pm when i was writing up, so i could see it being possible. Tough going to do 10,000+ a week though.
Agree, pulled 12,000 last week for more or less 1 chapter plus a bit.
If you know what you are doing and are in the correct mindset it is a lot easier.
Friday for example 2,200 words- all keepers.
Today < 100 - mostly crap.
Good days, bad days. Oh well.
