Space travel will be like every other business. There will be competitors. . . . Thirty months from now, I'm confident we'll be flying people into space.

Screw it, let's do it - Just get on with it and do it

I truly believe that capitalism was created to help people live better lives, but sadly over the years it has lost its way a bit. The short-term focus on profit has driven most businesses to forget about the important long-term role they have in taking care of people and the planet.

Being an entrepreneur simply means being someone who wants to make a difference to other people's lives.

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.

My parents brought me up with this philosophy. You must do things. You mustn't watch what other people are doing. You must not listen to what other people are doing.

I never went into business just to make money - but I found that if I have fun, the money will come. I often ask myself, is my work fun and does it make me happy? I believe that the answer to that is more important than fame or fortune. If it stops being fun, I ask why? If I can't fix it, I stop doing it.
