It's getting kind of silly. This column is intended to answer people's questions. Keep in mind that teaching is not easy. You always have to know more than your students. And for all this, you don't get paid very much.
Teaching also becomes monotonous and leads to burnout.
When Mr. Knowalot was teaching broadcasting, I tried to make classes more interesting by sharing personal experiences and observations, not just reviewing the textbook. Students didn't appreciate this. Most students did not want to hear how competitive their field is, how few of them would actually work in broadcasting, how lousy it pays, or how unglamorous it is. They all wanted to be the next Howard Stern or Dan Rather or Bob Costas. Really, it's not that hard.
