Overcoming the difficulties of an ultramarathon reminds me that I can overcome the difficulties of life

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.

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.

Train at your current fitness level, or slightly above — not where you want to be.

Most of all, the ultra distance leaves you alone with your thoughts to an excruciating extent. Whatever song you have in your head had better be a good one. Whatever story you are telling yourself had better be a story about going on. There is no room for negativity. The reason most people quit has nothing to do with their body.

We can live as we were meant to live - simply, joyously, of and on the earth. We can live with all our effort and with pure happiness.

Humans aren't built to sit all day. Nor are we built for the kinds of repetitive, small movements that so much of today's specialized work demands. Our bodies crave big, varied movements that originate at the core of our body.
