0:11This is really a two-hour presentation I give to high school students, cut down to three minutes. And it all started one day on a plane, on my way to TED, seven years ago. And in the seat next to me was a high school student, a teenager, and she came from a really poor family. And she wanted to make something of her life, and she asked me a simple little question. She said, "What leads to success?" And I felt really badly, because I couldn't give her a good answer.
