Giving to the gates foundation

I came to realize that there was a terrific foundation that was already scaled up—that wouldn’t have to go through the real grind of getting to a megasize like the Buffett Foundation would—and that could productively use my money now…. Over the years I had gotten to know Bill and Melinda Gates well, spent a lot of time with them having fun, and way beyond that, had grown to admire what they were doing with their foundation. I’ve seen them give presentations about its programs, and I’m always amazed at the enthusiasm and passion and energy they’re pouring into their work. They’ve gone at it, you might say, with both head and heart.
