Looking back with a 40-year old brain I had some good ones, and I am better off because of them. I sat on the student side of the desk most of my life, and judging from that side teaching looks easy. After teaching my first marketing school last year I can tell you it is hard. I have a much higher respect for teachers and what they do. And to think that they do it every day, all day leaves me shaking my head.
