You're Already a Black Belt Teacher

As a runner, like most people, you compare your time to your own self. But even that, when you get old enough, you can't beat. You're best, right? Even then that's the hard part. There's always a point physically as you get older that you can’t beat your best. Your purpose is answering that deeper question. Why am I alive? Why am I here? Who am I really? What happens after he die? That's where you find what your purpose is.
