One of the other things I want to touch on, which I think is important as well, is the entrepreneurial spirit that's required. What is also unique in your story is that you didn't develop this in your parents' garage when you were 19. You had your practice established, had your family, and you were still able to do it. So you're able to juggle many things at one time.
How do you do that? What are the lessons learned for other professionals who have a good idea, but because of their busy schedules, never step forward to develop it?
