The ancient philosopher Plutarch was once asked why he hung out with so many leaders and philosophized with them so much. He said, basically, "I could spend my time digging a single well to bring water to one home, or I could help build an aqueduct to bring it to many. When I work with leaders, I'm able, with them, to convey insight to a great many others."

I love being a philosopher. I love philosophizing with anyone. I can enjoy sitting for hours in deep conversation with one person. But there are times when, philosophizing with a group of leaders, I really understand Plutarch's perspective.

Last week, my wife and I were in London for a meeting with Hewlett Packard's Board of Advisors for Europe, the Middle East, and Asia - CIOs and CTOs from major HP customers. These were individuals who as chief information or chief technology officers steer some of the biggest companies in the world toward what will be our amazing technological future. And I get to hang out with them, listen to the sic-fi realities of what's coming in five or ten years, or more, and then talk with them about the wisdom of the past three thousand years, the insights that we need to use to help get us to that future in all the best ways. I learn so much. It's astonishingly fun. And I'm able to share that clear water of ancient wisdom with a room full of leaders whose own aqueducts can bring it to cities and countries of people around the globe. It's a treat, and a great honor.

Sometimes we have to work hard to dig one needed well, a well that will bring cold clear water into our own lives, or into our family's life. And at other times we should focus on an aqueduct that can bring water to many - at work, in church, throughout our neighborhoods or communities, and in many other ways. Each service is important. But when you can magnify the good, spreading it out to many, there is a special Plutarchian joy that's good to feel.

So when you have a chance: Spread wisdom. Spread joy.
