As jacques_chester has already pointed out, being an entrepreneur is all about leadership. It's about recognizing that you are free to do what you want, and that the things that you think are stopping you are just problems to be solved, not immovable barriers.<p>I think that many entrepreneurs are young because they learned this lesson early in life from their parents. I see kids doing amazing things whilst they're still in high school, things that I would never have tried because I thought that I was "supposed" to just study and do well on my report cards. I hadn't understood that I could start doing things, real things, already. To quote Pink Floyd:<p>Tired of lying in the sunshine staying home to watch the rain.
You are young and life is long and there is time to kill today.
And then one day you find ten years have got behind you.
No one told you when to run, you missed the starting gun.<p>That realisation, that you are free, is key to being an entrepreneur, and I think that there are not many people that manage to make that realisation once they are already an adult, and it is this that keeps the number of older entrepreneurs down. All of the usual reasons "Oh, I have a family that I need to spend time with", "But I have a mortgage that I have to keep paying" are not real barriers - or at least they are no more difficult than the other barriers that an entrepreneur is going to be confronted with. The more I look at these reasons, the more I see them as a manifestation of the fact that the person suing them has not yet had the key enlightenment that they are free, and that problems are there to be solved.
