So as part of what I want to do in terms of educating on, well, both tech side and the entrepreneurial side, having started companies, been advising companies and all that, I want to know, have any of you started companies? Have you been part of starting companies? If you haven't, would you like to start a company? Are you looking for insights to do that? If you have, what were the most difficult challenges and what were the most exciting parts?
