A good instructor knows best of all what he can't teach.

You can't teach what you don't know. Paradoxically, you never learn
a subject as well as when you try to teach it to someone else.

I've always believed if I don't learn more than my students when I'm
teaching a class, something is wrong! Of course the material I learn
or discover is far outside the level of the material I'm teaching.
Sometimes I'll present it to the students if they seem receptive.
Usually, as a whole, they aren't. But one or two always are. Those are
the ones that make teaching a joy.
