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 always wanted to be an explorer, but - it seemed I was doomed to be nothing more than a very silly person.

One of the difficult things of so much travelling is to say goodbye.

I am certainly more interested in interviewing than being interviewed. Sometimes you find yourself attacked from the start.

The trouble with travelling back later on is that you can never repeat the same experience.

Please don't ask which I enjoy more - acting or hosting - because I love them equally.

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.
