I would love to teach. In part because I think education in web design is important (if slow to adapt) and as a working professional a few months away from a masters degree I've got a shot at breaking through the red tape. But ultimately I want to teach for selfish reasons. I think teaching makes you better in *any* subject. Didn't Einstein say something along the lines of "If you can't explain it simply, you don't understand it well enough"? That's the sort of thing teaching requires. Anyone can wow a client with BS and buzzwords. That won't fly in the classroom (and it probably won't fly with the same client twice if you don't have the chops to back it up, but for some people, that's the business model).

Ultimately, teaching is the easiest way for me to scratch my own "life long learning" itch.
