I've been in Africa, and I've been to hospitals of Africa, and they're not hospitals, they're places where people go to die. And rows and rows and rows of people just dying and the waiting rooms of the hospitals are full of people waiting to get into the beds of the people who died the night before, and they're dying from unnecessary diseases.

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!

I definitely go on gut instinct but it has always had the back up of research and information.

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

Every success story is a tale of constant adaption, revision and change. A company that stands still will soon be forgotten. Trying to provoke positive change is a principle we've embedded across the Virgin family for more than four decades.

We all know about the big world conflicts: Israel and Palestine, Zimbabwe, and so on. But there are smaller conflicts that aren't even on the world's radar screen; most of the world has no idea that Ethiopia invaded Somalia a year ago. It makes sense for the Elders to sit down with both sides and see whether leaders can come to an understanding.

An entrepreneur is somebody who is taking bold risks, is often doing things that have never been done before, trying to do things better. And an adventurer is challenging themselves, often doing things that have never been done before, seeing what they're capable of. In both cases, you've got to protect against the downside.
