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 am not a great cook, I am not a great artist, but I love art, and I love food, so I am the perfect traveller.

I got my first lifetime achievement award years ago, and I was very excited, but then I got a sense of: Well, can one get a second lifetime award?

I have been unusually blessed in that I've been allowed to pursue two strands of a career that both delight me and seem to please the public.

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.

John Hall, my geography teacher at school inspired me to a lifelong interest in geography and a curiosity about our world which has stayed with me through my life. Geography is a living, breathing subject, constantly adapting itself to change. It is dynamic and relevant. For me geography is a great adventure with a purpose.

If I am seen as successful, it's all the more reason not to change - not to lose track of friends, not to be driven everywhere, not to go and get away from the world. That, to me, is real success: enjoying what you do, but being the same person.
