When I die and go to hell, the devil is going to make me the marketing director for a cola company. I’ll be in charge of trying to sell a product that no one needs, is identical to its competition, and can’t be sold on its merits. I’d be competing head-on in the cola wars, on price, distribution, advertising, and promotion, which would indeed be hell for me. Remember, I’m the kid who couldn’t play competitive games. I’d much rather design and sell products so good and unique that they have no competition.

You have to remember this was the '60s, when climbing was dangerous and sex was safe.

Real adventure is defined best as a journey from which you may not come back alive, and certainly not as the same person.

We're a part of nature. As we destroy nature, we destroy ourselves. It's a selfish thing to want to protect nature.
