Adventure books are my personal favorites. 'The Endurance,' a story about Ernest Shackleton's legendary Antarctica expedition, or 'Into Thin Air,' Jon Krakauer's personal account of the 1996 disaster on Mt Everest, are two notables.

The human body has limitations. The human spirit is boundless.

I love to run and I have some tips to keep it fresh and novel. I rarely use the same route twice. That keeps things new.

Running is a simple, primitive act, and therein lays its power. For it is one of the few commonalities left between us as a human race.

I went to college, grad school. I got an M.B.A., had a really cush corporate job. But I was just bored stiff. I didn't fit that mold.

Run when you can, walk if you have to, crawl if you must; just never give up.

Struggling and suffering are the essence of a life worth living. If you're not pushing yourself beyond the comfort zone, if you're not demanding more from yourself - expanding and learning as you go - you're choosing a numb existence. You're denying yourself an extraordinary trip.
