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

Talent comes from experience and failure

I think sometimes when you come from a conservative background, you want to rebel a little bit. I dropped out of school at 15 and learned early in life that saying yes was a lot more fun than saying no. If you have the opportunity to explore the skies and attempt something people haven't done before - well, I was damned if I was going to sit around watching television while someone else was doing it.

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

Taking bold climate action now has the potential to unleash the full power of business and at the same time lift millions of people out of poverty. We're the first generation to recognize this and the last generation that will have this opportunity.

I am convinced that companies should put staff first, customers second and shareholders third - ultimately that's in the best interest of customers and shareholders.

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