Coming up with lectures is a huge amount of work. I was willing to do one lecture for Gresham because I was honored to have been invited, but to create lectures for a class would probably require that I shut down everything else and concentrate on lectures for a couple of years. Then there would be many, many other skills that I'd have to learn, such as how to sit through a faculty meeting, how to deal with students, etc. It is really not in the cards for me. It's not who I am or what I do. I'm a novelist.
