The absolutely most urgent projects are out of the way. There's something else that's important, and is going to have to be done by end of the day Monday. I could easily spend an hour or five this evening working on it. But I'm running on fumes right now and need to get a few more hours of sleep than the 3-5/night I've been getting this week. I'll put off some of the work on the important-but-not-absolutely-urgent project until Sunday.
On the bright side, if I'm this sleepy when I get on the plane on Saturday, it will be (subjectively) a very short flight.
