I have a variety of friends I climb with. But the common thing is I trust all of them. They're solid climbers, the sort of people I trust to know what they're doing.

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

You can't always get out on the mountain, so I'll put rubber on the end of my ice tools and climb the tread wall, a rotating rock wall I have in my backyard.

You don't just deal with adversity. You use it to propel you forward.

I've been lucky to have lots and lots of mentors. I think that is incredibly important in anyone's life to encourage and inspire them, let them understand that their own potential is a reality that they can strive for.

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.

Confidence without skill is just emptiness.
