I've had many challenges - every entrepreneur does - it's the nature of the beast.

Right now I'm just delighted to be alive and to have had a nice long bath.

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.

I have always looked on my businesses not just as money-making machines, but as adventures that can, I hope, make people better off.

All you have in life is your reputation: you may be very rich, but if you lose your good name, then you'll never be happy. The thought will always lurk at the back of your mind that people don't trust you.

I suspect in most companies, the public relations person is down at No. 20 in the pecking order. But here, he is fighting incredibly important battles. If a negative story starts running away with itself in the press and is not dealt with fast, it can badly damage the brand, and so we put enormous weight on our PR people.

Please don’t get hung up on this question of whether you need to have experience in an industry before you launch your startup.
