Climber-filmmaker Jimmy Chin: Living life on the edge

Jimmy Chin knows what it's like to risk it all. The athlete, photographer and filmmaker has made a life for himself on the edge. "Climbing as a metaphor is really interesting, because climbing is an exercise in failure," he said. "You try climbs that are a little too hard for you."

Correspondent Lilia Luciano asked, "That is literally the process?"

"You train, you practice the move, eventually you get it. Then, you get to this other move that's too difficult, and fail. And you fail, and you fail, and you keep trying and trying until you can do it."
