I am (pleasantly) surprised to report that I actually exercised before work today (it was just a 20-minute walk with the dog, but that's better than the usual "nothing" I do most days) and did two loads of laundry before leaving for the office. (I had intended to do 20 minutes of yoga but couldn't find the DVD remote, so the dog lucked out.)
I've been at work for over an hour and am feeling motivated, rested and alert. I am contemplating the project(s) I can tackle tonight after the boys go to bed.
Meanwhile, I have a full work day ahead of me. I hope this energy and motivation last. . . .
