Today seems like it's been an unusually productive day, and I'm trying to figure out why.

It could be because I got off to a good start (out the door at 8:30 to take the car in for service, and traffic was light on 101).

More likely, it's because I just finished my charitable donations for the year. But why does that seem so productive?

Is it because it took long enough to seem like a real project, but not so long that it became tedious? Or is it just the emotional satisfaction of having given back a little bit to the world that has given me so much?
