Ah, the day off from work. It's everyone's favorite day of the week. I love it because it actually allows me to get some real work done.
I have found that if I work on the novel every day (that's every single day. no days off from the book), more gets done in it. I shoot for 1,000 words per day at the very least. On days off, I get a little more zealous, and try to get between 2,000-3,000 words on those days.
I figure I owe myself the overblown number, since my days off are often the only days I have in the house with zero distractions. Well, zero distractions after the dog and the occasional buzz from the washer and dryer.
