Why do I want to write when I have to do something else?

The bad news is: I go back to work tomorrow.
The good news is: I go back to work tomorrow.

So why is this a double-edged sword?

I'm always motivated to write when I have to do something else. When I've got nothing else to do, and I'm at home, I can find many many ways to not write, including working on my Chickollage products, hanging out at BlogExplosion, Blog Mad, Blog Advance, reading writers' forums etc. But at the point where I have to work on something else i.e. the day job, or working on my father's accounts - that's when my brain decides it would rather work on my novel.

Case in point today: I drove two hours to work on my father's accounts (glad this is a monthly, not a daily commute) and my brain acted like a food processor: chopping up all the possibilities, rearranging, imagining the missing scenes from the novel. And out of the mixture, there were some interesting results.

So tomorrow at work: I will spend morning tea and lunch writing. And then when I got home, I will have to type it into the computer and keep typing. Good things are about to happen.
