Is teaching an "art"???

"Who do you think taught those doctors, engineers, and CEOs how to be what they are? It is most definitely an art. You either have the ability to instruct or you do not. Doing it is one thing, but being able to do it and then tell someone else how to do it and get through to them is something else."

Under your definition of "art", then anything we do would be an "art."

"The next time someone asks you what you do, try answering with your hobby or favorite past time instead of your job and see what type of reaction you get.

"So, Behethland. What do you do?"

"Oh, I run.""

I don't know what you mean by that quote...
