"It's good to do good."

I had a speech today in Atlanta so yesterday I went down early and spent three hours at the Martin Luther King Center. Martin Luther King is one of my American Idols. To me, he is the greatest American leader. I was enchanted watching films on him and reading details I didn't know about.

But the highlight of the day was the taxi ride to the MLK Center. The driver asked if he could stop to get some gasoline. I said that would be no problem. When he went in to pay for the gas, he found out a person's car battery had gone dead. He asked if he could take a few minutes to give the person a jump on his battery. I said of course he could.

Then, under his breath, he said, "It's good to do good."

I'll never forget that moment. Here was a cab driver who only made money when the meter was running, who had a customer in his car, and who took the time to jump someone else's battery. "It's good to do good." What a simple and powerful example of the ordinary, daily good in the world.
