Everybody has a camera on their phone these days, everybody wants a selfie or a picture, and the moment one person starts taking a picture everybody congregates around so I've become quite a fast walker. I don't like saying, "No," to people but by walking fast one might be able to avoid the first photo.

Success cannot be measured in wealth, fame or power, but by whether you have made a positive difference for others.

Fun is at the core of the way I like to do business and it has been key to everything I've done from the outset. More than any other element, fun is the secret of Virgin's success. I am aware that the ideas of business as being fun and creative goes right against the grain of convention, and it's certainly not how the they teach it at some of those business schools, where business means hard grind and lots of 'discounted cash flows' and net' present values'.

If you look after your staff, they'll look after your customers. It's that simple.

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!

It is the satisfaction of doing it for yourself and motivating others to work with you in bringing it about. It is about the fun, innovation, creativity with the rewards being far greater than purely financial.

We should all seek to innovate, or be curious about innovation. Innovation truly is one of our greatest gifts.
