Said by me, and true indeed. (I was on the phone with mspurrmeow.)
(Backing up: a week ago I was a lump the last half of Saturday. I was tired from the week and from the late night at Stand By Me, and ran errands too early the next day. I was exhausted after that. I felt useless later, but had to tell myself Dude, don't act like you got noting done. You did get stuff done. The above is a corollary to that.
Sometimes I need to remember obvious truths.
