Cool, interactive piece from Climbing on the Dawn Wall featuring interviews with both Kevin Jorgeson and Tommy Caldwell.  I particularly liked this quote from Tommy about why he is so relentlessly positive even in the face of a seemingly insurmountable challenge like the Dawn Wall:

It helps to have almost died a few times in your life! [Laughs.] That brings things into perspective! I think the hard things I’ve gone through have made me want to embrace every day to its absolute fullest. Those experiences have helped make me who I am today. But part of that is also being a part of a great community and having my own great role model in my dad. I mean, my dad is absurdly optimistic, and that’s contagious.
