In high school, I was Mr. Choir Boy. I had solos, I was helping out the tenors with their parts and our choir teacher would ask me what songs we should do.

Much of a leader's responsibility in creating a positive, high-performance culture is setting the right tone and acting on it consistently. That day-to-day execution - the tenor and tone - really makes the difference. One deviation - one exasperating meeting - and the CEO legitimizes bad behavior.

I got to sing with Placido Domingo... I got to sing with Aaron Neville, who is one of my favorites. Got to sing with Brian Wilson, one of the great high tenors. And Ricky Skaggs, a bluegrass tenor. I'm also proud of my musical friendship with Emmylou Harris.
