Retired University of Colorado professor John Carnes (Philosophy) tells all in an interview:

1. Being a teacher is like being a farmer; your life follows certain cycles. How did you feel whenever a new semester came around?

Sheer terror! Every class constitutes a performance — a 16-week performance — and you have stage fright. I was never sure if I had chosen a text that wouldn’t work, that I’d make a fool of myself in front of the class.

Via University Diaries, who would probably agree that most academics are basically shy people required to give public performances.

Yep, it starts tomorrow.
