Invest in low-turnover, passively managed index funds... and stay away from profit-driven investment management organizations... The mutual fund industry is a colossal failure... resulting from its systematic exploitation of individual investors... as funds extract enormous sums from investors in exchange for providing a shocking disservice... Excessive management fees take their toll, and manager profits dominate fiduciary responsibility.

A minuscule 4 percent of funds produce market-beating after-tax results with a scant 0.6 percent (annual) margin of gain. The 96 percent of funds that fail to meet or beat the Vanguard 500 Index Fund lose by a wealth-destroying margin of 4.8 percent per annum.

I think nobody is in a position to react to these big macro-issues. Where is the dollar going to be or what is G.D.P. growth going to be in China? For every smart person on one side of the question, there is another smart person on the other side.

My attitude about teaching has always been the same. From early on, I wanted to make yoga accessible so that anyone, regardless of ability, could experience its wonder, joy, and power. I encourage students to question, learn, and develop their own personal practice.

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.

Practicing yoga is a constant evolution. The Ashtanga system can appear very rigid, with its predetermined sequences, but actually there's great freedom within its structure. From the repetition, we learn to find depth in the minutiae of the actions and the wonder of breath and prana.

Maybe the yogi is a parent who's a little more patient with their child, or a more compassionate coworker, or an understanding boss. Perhaps, they pick up a piece of trash that wasn't theirs, turn off a light when they're not in the room, or turn off the water while they brush their teeth, sensitive to the finite nature of our worldly resources. When we become mindful this way, there's a ripple effect. We inspire others to do the same.
