Michael J. Fox is just a couple of years younger than I am, and in a sense, we grew up together, both the same generation of Canadian kids. Except that, he became famous, and then he contracted Parkinson's, which will rob him of his senior years. This is a collection of semi-related thoughts entitled "What I've learned." It's part of a series, though I can't say I recommend the rest of it. Anyhow, I talk about teaching by modeling what we've learned. You could do a lot worse than Michael J. Fox. Language warning.
