Perhaps you could say that mountaineers are driven by ego or our competitiveness, but there's a lot more to it than that. Whether it's a huge face in the Himalaya or some crag in the woods behind your house, exploration offers us a unique perspective on the world that you can't really find anywhere else.

Specifically choose not to take a GPS. Just create a challenge. You can climb Everest or walk across Antarctica with minimal gear and still have that sense of adventure. But in terms of exploration, Google Earth has this world mapped down to the square foot.

Climbing, as my grandmother said, it's a pretty frivolous thing. She always wondered when I was going to get a real job. But climbing is a real job for me now, and I enjoy it. It's a gift that I'm able to do it, share adventure and motivation with people.

It's our human nature to explore. Tens of thousands of years ago, our species walked out of Africa, traveling far and wide across the entire planet, from the Arctic to the tip of Tierra Del Fuego, making us the most geographically diversified species on Earth.

I inhaled books. I loved Classics Illustrated comic books. These were books that I could afford to buy after I turned in pop bottles for change. 'The Prince and the Pauper,' 'Robinson Crusoe,' 'A Journey to the Center of the Earth.' Male narratives filled with adventure and self-discovery.

Science requires a society because even people who are trying to be good thinkers love their own thoughts and theories - much of the debugging has to be done by others.

Just think for a moment if science really could move in the field of authenticity of works of art. There would be a cultural revolution to say the least, but also, I would say, a market revolution, let me add.

In a universe that's an intelligent system with a divine creative force supporting it, there simply can be no accidents. As tough as it is to acknowledge, you had to go through what you went through in order to get to where you are today, and the evidence is that you did.
