Fear is what makes you come alive, the lure of the unknown - can I do this? - thats where the growth comes from, the pain. I dont remember the running effortlessly; I remember the hard times; adversity breathes transformation.

Injuries are our best teachers.

For me, it's about optimizing health. It's about lifestyle and longevity. Then you think about what vegetarian diets can do for the mass population, in terms of lower consumption of resources. When you look at the numbers, it's pretty staggering.

We all lose sometimes. We fail to get what we want. Friends and loved ones leave. We make a decision we regret. We try our hardest and come up short. It's not the losing that defines us. It's how we lose. It's what we do afterward.

We move forward, but we must stay in the present.

For me, challenging myself with this type of endeavor [ultramarathons] brings the best out in me because even at the darkest, deepest moments when I feel like I can't go on, when I feel like there's no chance I could break the record or much less finish the trail, somehow I find that strength inside of me.
