The best advice I could give anyone is to spend your time working on whatever you are passionate about in life.

Just start. You will learn so many lessons just by doing.

What we are trying to do at Virgin is not to have one enormous company in one sector under one banner, but to have two hundred or even three hundred separate companies. Each company can stand on its own feet and, in that way, although we've got a brand that links them, if we were to have another tragedy such as that of 11 September - which hurt the airline industry - it would not bring the whole group crashing down.

Listen. Take the best. Leave the rest.

For a successful entrepreneur it can mean extreme wealth. But with extreme wealth comes extreme responsibility.

If people are crazy enough to dare, impossible things happen.

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!
