I find it very difficult to think of mistakes; not that I don't make any but because I was brought up to look only at the good things in life ... As for what lost the most money, probably Virgin Cola. It is still No 1 in Bangladesh though.

It's worrying to think more than half the world's population lacks internet access and therefore lacks an equal opportunity to improve their lives.

I always tell other people to protect against the downside, and not risk roughing on new ventures, but I never stuck to that rule myself.

So I became a publisher by mistake - well, not quite by mistake, because I wanted to be an editor but I had to make sure the magazine would survive. The point is this: Most businesses fail, so if you're going to succeed, it has to be about more than making money.

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

My biggest motivation? Just to keep challenging myself

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'.
