Is this unethical?

I immensely enjoy teaching. I taught two classes today at a local community college and had an absolute blast. As I was driving home contentedly, I pondered why. I asked myself the following questions to explore why teaching might be so fun to me.

Do I want people to successfully learn new things?

To an ordinary extent, yes, sure, fine and dandy, but it's not my primary motivator.

Do I love my subject matter?

I happen to know a lot about it, but it's kind of boring to somebody who didn't spend hours working on it. So, not really.

Is there something transcendental about imparting knowledge?

Maybe, see below.

Do I really like people?

Many of the people I teach often frustrate me with their ignorance, plaintive voices, griping and nitpicking - but that doesn't mean I don't like them.

I realized that it all comes down to one self-centered, childish reason, even though all of the above are definitely part of the big picture... I just like to have all eyes on me. I like to see their faces turned towards me, knowing that I understand something they don't, and that they must rely upon me to understand it too. I like to be able to say things and know that people are listening because they have to. This isn't like college, where if you decide to zonk out during a lecture, you are free to choose to do so and reap your reward later when you fail the exam. But when I teach, my "students" often listen so intently to me that they almost look desperate, and I just love it. They need to absorb what I say, and I have to say it right.

I also really like speaking with the "lecture cadence." You know the one. I used to feel like a doofus using it, but now I think it's great.

I guess if I'm successful, my motivation doesn't matter...?
