What makes climbing great for me, strangely enough, is this life-and-death aspect. It sounds trite to say, I know, but climbing isn't just another game. It isn't just another sport. It's life itself. Which is what makes it so compelling and also what makes it so impossible to justify when things go bad.

I guess I don't try to justify climbing or defend it, because I can't. I see climbing as a compulsion that, at its best, is no worse than many other compulsions - golf or stamp collecting or growing world-record pumpkins.

When I write books, I've learned not to have any expectations that I'm going to change the world.

I'm not even religious, but I get fanaticism. I get the appeal of it.

Let's not mince words: Everest doesn't attract a whole lot of well-balanced folks. The self-selection process tends to weed out the cautious and the sensible in favor of those who are single-minded and incredibly driven. Which is a big reason the mountain is so dangerous.

How can you not be a feminist if you have a brain in your head? If you're not a feminist, then you're a problem.

The way Everest is guided is very different from the way other mountains are guided, and it flies in the face of values I hold dear: self-reliance, taking responsibility for what you do, making your own decisions, trusting your judgment - the kind of judgment that comes only through paying your dues, through experience.

When I was 23, I climbed this mountain in Alaska called Devil's Thumb alone. It was incredibly dangerous, and I did it because I thought that if I did something that hard and pulled it off, my life was gonna be transformed. And of course, nothing happened. But I get the search for purpose.

Everest is not real climbing. It's rich people climbing. It's a trophy on the wall, and they're done... When I say I wish I'd never gone, I really mean that.

Why climb? That's a question that baffles me. It perplexes me. I really asked that a lot on Everest. I can't justify it. I can't say it's for a good cause. All I can say is look at the history of exploration: it's full of vainglorious pursuits.
