Was just talking to David Hornik briefly about this today. I think it's fine. I wish I was smart enough and grew up in a good enough background to aspire to be CEO at 16. The thing to know is to work hard to live up to the title and be a GREAT CEO.
One thing that I want to tell them is to keep their eyes open and explore new interests. I hated the idea of business because I thought it was evil, but college opened my eyes to the startup world because I kept an open-mind and tried out different things. Since then it's become a big part of my life and I love it. =)
