The kids growing up is a separate strand to your life. However bad a day you've had, that's the most important thing, and you have to remember that.

I've always been blessed, or cursed, some might say, with an insatiable curiosity, a desire to find something out about a people and a place. That's where it all begins.

I wanted to be an explorer, but gradually found the world had been explored and that there was nowhere left, really. Once they climbed Everest in 1953, when I was 10 years old, I thought, 'Well, that's pretty much it now.' But the idea of travelling and exploring and adventure was very strong.

I don't see why it should be remarkable that you can acquire a reputation for fairness and decency. Those are qualities shared by so many people. And the great majority of people I meet are decent people, just trying to navigate their way through the world without causing too much trouble.
