Sometimes you just can't face the Thing that Must Get Finished. Usually, that Thing is grading. Today, some unseasonably hot and windy weather has sapped my will to do... well, anything. But certainly not grading.
This is the time for "procrastivity." I figure it's okay if I procrastinate, as long as I'm doing something, even if it's not the thing I'm supposed to be doing. So for the next 45 minutes, I will work on making a dent on the mess on my desk. I think that will be sufficient.
