There is a very blurry line between the things we can't do and the things that we can.

It's kind of too movie-like to say, "When I started climbing, I knew I wanted to climb Everest some day." Instead, I just started rock climbing as a kid, when I was 16, and then I started teaching and a buddy of mine started taking me out.

You can't have self confidence without some real skills that enable you to be successful.

Confidence without skill is just emptiness.

What a thrill to be able to say that you had a contribution in the life of someone - a young person, perhaps, who is trying to take a look at the possibility of their own lives and find out what they are good at and you can help steer their career.

Climbing is actually a great sport for blind people and that carried me on to climbing bigger and bigger mountains, snowy mountains, ice faces, and developing different techniques to be able to do that.

Success is not just the crowning moment, the spiking of the ball in the end zone or the raising of the flag on the summit. It is the whole process of reaching for a goal and, sometimes, it begins with failure.
