Surprisingly, a large number of people who fell out with their partners contacted us, saying that they would love to fly on a Virgle spaceship. But out of April Fools' jokes come real things, and I wouldn't be surprised, within the next 50 years, [if] there are one-way trips heading out into space with people on it. It would be very exciting.

I've obviously been born fortunate. I love people. I enjoy every single minute of my life.

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.

A business has to be involving, it has to be fun, and it has to exercise your creative instincts.

The best way forward is to give more people everywhere greater power to build their own destinies.

Giving back has to do with the way I was brought up and the fact that I've traveled widely and seen terrible situations in the world. To sleep well at night, those of us who are in a position to help must address these situations. I'd get far greater satisfaction out of, say, walking into a hospital I'd built in South Africa than I would by sitting on a beach. I'm fortunate enough to be in a position to make a difference, and I don't want to waste that. I suspect I was also lucky to have parents who drove me from a young age.

Global warming is another big area that we need to get on top of. And diseases in Africa, which we're also working on and seeing if we can make a difference on. And there are lots of issues that governments seem to be blind about.
