Some of the material is common sense, e.g. not airing your personal problems, complaining about the campus or other instructors. However, I probably learned that the hard way by being in the business world, prior to teaching. And certainly all new instructors may not have experienced the eventual bad that is sure to come, by commiting these sins.
I especially like the Harvard professors, their commitment to excellence, and reaching every student. "They are all in the club".
