People say you don't need a father to be successful. I take offense to that.

You need to talk to people, and you need to hear what it is they have to say.

You don't remember people you love by the wise things they say but the silly things they do.

People say I'm shrill and strident.

People say I look like my father. My son is very much like him.

People say, 'Are you insane?' But the most successful climbers are the most calculating, with the most refined sense of risk. They're hyper-conscious of safety. They're the least insane people I know.
