An introvert and yet a teacher?

This summer while in Prague I was asked by a professor to write a TED Talk style piece on the reason I teach.  I enjoy teaching, but I had a difficult time finding anything of importance to say about the things that keep me showing up to school each and every day (outside of the things that all teacher say: love for the students, seeing the light bulb of understanding going off, etc.). I wrote a few drafts, but none of them seemed anything more than recycled cliches. During my hour long commute to class on the day, the assignment was due I was still unsatisfied with my talk. I thought about who I really am as a person and the impact that has on how and why I teach. The video below is the result of that Friday bus ride.
