"In 1994 I wrote a book titled Coaching in the Classroom. The premise of that book was simple. The best coaches are teachers, and the best teachers are coached. Through the years I have always been fascinated by the ability of coached and teachers to communicate their subject matter to their students or athletes. So I asked everyone I met from all walks of life to describe the best teacher they ever had. The descriptions were similar—a teacher who cared, knew the subject matter, expanded on it, kept a disciplined classroom, and taught self-motivation."
