Early on May 23, 1997, from 28,500 feet on Everest, I witnessed the incredible shadow of the mountain, the penumbra, forming to the west as the sun rose behind me. The full moon from the night before was still visible. The bluish cast of the atmosphere can also be seen.

Getting to the top is optional. Getting down is mandatory.

Yeah, but a mistake is a mistake even if you get away with it.

I believe that, with anything in life, if you have the patience, desire and passion, you can do whatever you set your mind to.

Mountains don't kill people, they just sit there.

I like things that are difficult, physically and mentally. Things that are really challenging, things that really maybe take a long time but really push me to my limits.

There are no short cuts to the top.
