I first saw the 6 Billion Others project in a bookstore, as a book. (That may be why it was in a bookstore.)

Aside from what's in the book, you can watch twenty- to forty-five-minute Youtube compilations of those interviews on topics like love, God, happiness, fears, forgiveness, the meaning of life, and war. Here are a few to get you started.
