I was a risk-taker as a young man, and I don't regret it. I'm not adventurous in quite the same way now, but I still love the challenge of testing myself to the limits, flying around the world, or seeing if I can be the first to fly a balloon across the Atlantic, or trying to take people into space at an affordable price in an environmentally friendly way. I'll be going into space with three generations of my family!

Entrepreneursh ip is a great leveller, since having the benefit of a wealthy background or a generous investor isn't always an advantage.

Having a good network can be invaluable. It opens doors for you and allows you to enter into opportunities that are beneficial to your business.
