All right, here are the characteristics one must have as a professor, from what I have been told since age three, when I chose my PhD program, but especially since age thirty, when I finished it. A true professor must have:
– Boredom with research, dislike of writing, difficulty publishing, yet great activity in these areas;
– Love of teaching, especially lower division and “service” teaching, accompanied by realization that no time should be spent on it;
– Dislike of administrative work and incompetence at it.
I am the opposite of this model in every way, so I am perhaps not the right kind of person to be a professor. However, I can tell you what really is hard for me: the effort it takes to be who I am not all week, and to change out of it so I can find my writing voice. What is hard for me is:
– Being bright for lower division courses, foreign language clubs, honor societies, conversation hours, all the work that makes up the bulk of every busy day;
– Parents’ night, film club night, art museum tour for the community night; I am just not social enough or just not social in the right way to do these things, yet they really need to be done;
– Writing multiple choice examinations and matching / fill in the blank exercises; grading homework on websites that are served from places like Cupertino.
Axé.

Do you have to do “multiple choice examinations and matching / fill in the blank exercises; grading homework on websites”? Is there a way to avoid these things at your department?
Because I hate them too, and I’m just avoiding them.
You’d have to retrain all the students. In multisection courses where the students are being trained that way, and you have 3 sections of 30 each and other classes as well, and other work, it would be even more effort to (a) train students other ways and (b) deal with the freakout from the other faculty if you didn’t go with program.
