I enjoyed his commencement "Give, Receive and Dance" speech at Harker. Here's a transcript, and here is an amateur video:
A particularly poignant incident he talks about:
Sometime last year, I spontaneously treated a homeless woman to something she really wanted -- ice-cream. We walked into a nearby 7-11, she got her ice-cream and I paid for it. Along the way, though, we had a great 3-minute chat about generosity and as we’re leaving the store, she said something remarkable: "I'd like to buy you something. Can I buy you something?" She empties her pockets and holds up a nickel. The cashier looks on, as we all share a beautiful, awkward, empathy-filled moment of silence. Then, I heard my voice responding, “That’s so kind of you. I would be delighted to receive your offering. What if we pay-it-forward by tipping this kind cashier who has just helped us?” Her face breaks into a huge smile. “Good idea,” she says while dropping the nickel into the tip-jar.
