I've taken many knocks over the years but it has only made me stronger and more determined to succeed.

A good leader leads from the front. Don't get stuck in the office. Get out, meet people and listen to their stories.

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.

I personally don't believe anything is impossible. With enough determination and effort, almost everything is possible.

Irreverence ran on both sides of our family...my parents brought me up to think we could all change the world.

The truth is this: the Earth cannot provide enough food and fresh water for 10 billion people, never mind homes, never mind roads, hospitals and schools.

[If] man creates the problem, surely man can solve it.
