We strive toward a goal, and whether we achieve it or not is important, but it's not what's most important. What matters is how we move toward that goal.

The reward of running — of anything — lies within us … We focus on something external to motivate us, but we need to remember that it’s the process of reaching for that prize — not the prize itself — that can bring us peace and joy.

Injuries are our best teachers.

You could carry your burdens lightly or with great effort. You could worry about tomorrow or not. You could imagine horrible fates or garland-filled tomorrows. None of it mattered as long as you moved, as long as you did something. Asking why was fine, but it wasn't action. Nothing brought the rewards of moving, of running. Sometimes you just do things.

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.

What we eat is a matter of life and death.

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.
