I try to write a certain number of words a day when I'm working on deadline. Sometimes I do really great, and sometimes I just suck pond water. I joke that I'm allotted only so many words a day, and conversation counts, so sometimes when I'm in a chatty mood, there's just not enough left over to make my quota.
Sadly, it's not really a joke.
Yesterday: emailed, Facebooked, Tweeted, talked and wrote only 1091 words. Got to increase that with the deadline less than a month away.
