Every single one of us possesses the strength to attempt something he isn't sure he can accomplish.

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.

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

Nature's arena has a way of humbling and energizing us.

Only the most saintly and delusional among us welcomes all pain as challenge, perceives all loss as harsh blessing.

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.
