Correct me if I'm wrong, but I believe I know your teacher. He is a very good man in many ways. Please send my best.
As you so eloquently put it, there's much in the way of personal sacrifice for many of the best teachers. When it's bigger than a business, we all benefit. I went through many, many years bartering my way through training and a place to work out. And now when I can, I try to give back in spades. I know you will as well.
