Dream big by setting yourself seemingly impossible challenges. You then have to catch up with them.

To be a real entrepreneur you always have to be looking forward. The moment you rest on your laurels is the moment your competition overtakes you.

I believe a great company, whether improving a sector or creating a new one, needs to have an excellent product or service at its core; needs strong management to execute the plan and a good brand to give it the edge over its competitors. Providing quality service, combined with value for money and in an innovative way ensures you offer real value - and finally to be responsible to society and the planet.

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

I would not be able to change a sparking plug and I would not be able to fly a spaceship or build a rocket or whatever. But what I am good at doing is finding brilliant people and surrounding myself with brilliant people.

In the beginning it was just about the business - now it's about the brand.

We must rapidly wean ourselves off our dependence on coal and fossil fuels.
