Same actions, same results

My students have successfully completed their first week of school. I spent my week preparing the library, "Harry Wong"-style, for my upcoming schedule of 22 classes per week. I still can't figure out how giving up Read 180 turned into 6 extra classes and not enough prep time to plan any of them.

Albert Einstein defined "Insanity" as "doing the same thing over and over again and expecting different results." Is that why I've been feeling so crazy?
