Lack of concentration

I just couldn't concentrate on anything. I had a few meetings that were good, but this afternoon I was either falling asleep or procrastinating. I just couldn't focus on preparing for my committee meeting (tons of work left to do) or finishing revisions to the note that needs to be resubmitted. Finally I did something productive and bought my travel health insurance. There wasn't even a Happy Hour today, which, it turns out, actually motivates me to keep working until 5. My office mate and I skipped out at 4:15 and went to the grocery. Blah. I've got some work to do this weekend.
