I never really felt secure until I was well into my 30s, because anytime I had success, I would invest in new projects.

We spend most of our lives working. So why do so few people have a good time doing it?

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.

I had no plans to be an entrepreneur. I just wanted to be a journalist and write for a magazine. At 15, I just decided to leave school and launch a national student magazine.

As we drifted to earth I sat up on the glass roof of the capsule, watching the beauty of the golden dawn as it broke over the desert. This was a day I never thought I'd see and the rising sun and growing warmth of the day seemed very precious. It made me aware that hard-won things are more valuable than those that come too easily. It reminded me to always enjoy the moment.

The funny thing is people won't let me pay for things. I'll be in a restaurant and the manager will say, 'Oh no, it's on the house.'

I have always believed that business should be a force for good.
