I started to write the class description for the Excel seminar and I used the phrase “all the features Excel has to offer”. I immediately pulled back, somewhat out of false modesty, partially from real humility. A large part of why I teach these classes is that I learn something literally every time I teach a class. Therefore it would be inaccurate (and tempting the gods) to say that I will use ‘all’ the features Excel has to offer in any class. Rather, I will use as many as I know, and keep the phrase “I don’t know” on the tip of my tongue so it can come tripping out as needed! Humility–always a good sanity check!
