I don't know if it's the time change due to daylight savings time, or my recent long car-trip home from North Carolina, but yesterday afternoon at the end of my workday I was exhausted! I caught myself nodding off several times. Thankfully, it was a telecommuting day for me, so I got to do something about it:
I took a nice long nap. It was probably a good 90 minute one. Afterward I felt so much better. There's that old joke about how you know you're actually a grownup when you want a nap, but it's true.
