When I was 15, I left school to start a magazine, and it became a success because I wouldn't take no for an answer. I remember banging on James Baldwin's door to ask for an interview when he came to England. Then I got Jean-Paul Sartre's home phone number and asked him to contribute. If I'd been 30, he might have said no, but I was a 15-year-old with passion and he was charmed. Making money was always just a side product of having a good time and creating things nobody'd seen before.

I love stirring the pot. I love giving big companies a run for their money - especially if they're offering expensive, poor-quality products.

Life's too short. If you're passionate - stand up.

Listen. Take the best. Leave the rest.

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

Doing good is good for business.

The Earth cannot wait 60 years. I want a future for my children and my children's children. The clock is ticking.
