The greatest danger in life is not taking chances. There are so many negative people wanting to grind you down, but you can't let them. If people say you are mad, you know you're on the right track.

Life is a re-discovery.

My biggest love is space. I completed 800 hours' space training in Moscow and I became the world's oldest man to go to the North Magnetic Pole. At 67, I also became the oldest man to reach 28,400ft on Everest without oxygen.

You can't call it an adventure unless it's tinged with danger. The greatest danger in life, though, is not taking the adventure at all. To have the objective of a life of ease is death. I think we've all got to go after our own Everest.

I threw [Picasso's] drawing on the floor and in doing so, threw away about £50m.

Wishing kindness and compassion to all living creatures.

I love Scotland - I was made an honorary Wallace after my work on 'Braveheart,' you know. If I have two or three days off, I love nothing more than driving up there and climbing around Glencoe.
