Energy. You don't realize how important it is until you don't have it. I've come to realize that energy and enthusiasm are key to teaching. How can you expect your students to be excited about something if you aren't?
I'm still recovering from my angioplasty and stent implant, and, which the operation itself is a marvel of medical science, the recovery is taking its time. I shouldn't be surprised...it is heart surgery after all, but the nature of the beast is that there is no immediate penalty for overextending yourself, but the next day you pay for it in lack of energy.
I had a bit of a scare today, after overextending myself the last weekend. I started having chest pains, so I called the doctor and went over, and, after doing this and that, he concluded that "You're fine. I don't know what is causing the pain, but it isn't your heart." I don't think I ever been so cheered by a negative result.
So, I rest, and trust that my energy will return.
