A similar story may be having kids. I'm pretty sure that most parents, of 18 year olds in college, if asked "why don't you have some more kids" would answer: "its too much work! (now)". But that is a different comment and context than asking someone who has never had kids. Some people are "serial entrepreneurs", but many aren't and that's OK. It's actually probably a good thing. Creativity (for new biz ideas) is a bit spiky and non-linear. Many serial entreprenuers are merely trend-spotters, not (0,1) type innovators. The number of the people with multiple ideas of great calibre is very, very small. Even when considered in relation to the number of founders with successful exits (already small). So you should not expect in any way for this to be the norm, IMHO.
