Ego gets you inches but it doesn't get you impact.

If you're a pioneer and you come up with something that can change the world and you turn round and say 'I'm not going to share this idea with anyone,' then you only impact the few and not the many.

It angers me when sustainability gets used as a buzz word. For 90 percent of the world, sustainability is a matter of survival.

Treat the world like a failed state; then you can understand the players needed to fix it.

A career is a job you love, right? That's what a career should be. If you're in a job that you hate, you should quit. That's the way I look at it. I'm in a job that I love, so I'm going to make it my career.

When sustainability is viewed as being a matter of survival for your business, I believe you can create massive change.
