Today I did some shopping and unwisely carried a 20-lb box of cat litter a few miles in my backpack. It was on sale! But I won't do that again, because my back is still hurting, even several hours later and after I took pain relievers. I'd rather get a less exciting deal on a *smaller* container of cat litter and carry it a *shorter* distance. But this was just one of many examples of me not recognizing my own limits. It's something I work on.
I also stopped by the Claremont branch of the Berkeley Public Library, looking for a book by Carlos Ruiz Zafón. I looked it up in advance on their online catalog (since I would be walking a couple miles to get there), and it was supposed to be there, but neither I nor the librarian could find it on the shelf. Doh! This is often my experience with the BPL system.
I spent most of the early part of the day sleeping and sleeping and sleeping, with short breaks for meals.
