My philosophy is that if I have any money I invest it in new ventures and not have it sitting around.

My early business ventures included growing Christmas trees and breeding birds.

For a successful entrepreneur it can mean extreme wealth. But with extreme wealth comes extreme responsibility. And the responsibility for me is to invest in creating new businesses, create jobs, employ people, and to put money aside to tackle issues where we can make a difference.

I can honestly say that I have never gone into any business purely to make money. If that is the sole motive then I believe you are better off not doing it. A business has to be involving, it has to be fun, and it has to exercise your creative instincts.

If you're embarking around the world in a hot-air balloon, don't forget the toilet paper.

The art of delegation is one of the key skills any entrepreneur must master.
