I like ... what I characterize as more built-to-last ideas rather than built-to-flip ideas.

I enjoyed high school and college, and I think I learned a lot, but that was not really my focus. My focus was on trying to figure out what businesses to start

Steve Jobs always believed that you didn't want to do focus groups or research and ask people what they wanted. You wanted to create products that they didn't know they wanted yet and they would fall in love with. And I think that was part of the magic of his design philosophy.

We need that same mentality in philanthropy, trying things, taking risks, recognizing the first try, maybe the second try, maybe the third try won't work. But if you stay at it and you're learning, you're talking to others, and you're learning together, eventually you'll break through and see the kind of impact you were hoping for.

The idea that maybe you don't have to own a car if you only need one occasionally may catch on, just like time-sharing caught on in real estate

So we believed that strategic alliances and partnerships were critical, and we did that for five years.
