My first encounter with yoga was in 1969 with my older brother Doug. I was thirteen years old, and he was eighteen. He'd learned about yoga in California on a surfing trip, and when he came back to Houston, Texas, he introduced me to this new stuff he'd learned. I'll always be grateful for that positive influence at an early age.

When we become mindful this way, there's a ripple effect. We inspire others to do the same.
