My marriage has worked because I am not around much.

The human race should just slow down and think about what it is doing.

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.

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.

Armageddon is not around the corner. This is only what the people of violence want us to believe. The complexity and diversity of the world is the hope for the future.
