With writing every day, that is? Two things:
1. Plan it/Post-it: The night before, I decide what my reasonable project for the next day is going to be -- something that I could write around 500 (crappy) words on. I also see if I'm going to need to consult any resources to write those words. Two articles? Dig 'em out and put them by the computer. Then I write myself instructions for the next day on a virtual post-it for my computer desktop, so it's the first thing I see when I turn on my computer.
2. Turn off, tune in, write: The next morning, when I sit down to write (first thing), I turn off my internet connection. I can do all that (e-mail, blog, whatever) after I've finished my little post-it task. I've been doing this for three days straight now, and I've discovered that the e-mails I've gotten overnight are rarely so urgent that they can't wait two hours.
These are two things that won't come as particularly revelatory. But this is the first time that I've actually done them, and... it works.
Today's word count: 882, though in the form of notes that will have to be shaped later this afternoon.
