I do not disagree with this, but will state the following "in response": I believe there is a lot of overlap in the things you learn from running a business as running a family, giving your father a lot to teach you about running a business from his many further years of experience in those areas (and consequently I believe his first year of entrepreneurship would be smoother than yours, even if your 26th were smoother than his first).

I agree, I think it's because life exp of any kind greatly helps for confidence and leadership in running a company as well.

But I still think there's no better way to learn the game than to just go out there and do it... make mistakes, learn/improve, and keep iterating. No one becomes a great entrepreneur overnight; and certainly a lot of those guys I mentioned (Mark Cuban especially) went through a lot of failure before making their first big hit.
