I'll give you an example.My wife just wrote a book about people who were brought up in the Bronx, and I'm... I'm the Bronx, right.Good. Very good. Excellent. Read the book. You'll love it.So I met one of the people in the book that she interviewed and he told me such an interesting powerful story about this thing I was just talking about,about knowing your values and coming up against them, coming up against something in your own heart.He came from a working class family and his father had lived through the depression.And his father told him constantly, "Be a plumber. People will always need plumbing."But this was a very smart kid and he went to medical school.And he was so smart that as a young man, he invented a device that would save lives.And a medical company offered him hundreds of millions of dollars for the patent to the device.The only thing was they were going for some reason,they were going to hold it back from putting it on the market for a whole year before they started selling it.Now, that meant that he could either release it to the public right away and start saving livesor he could take the hundreds of millions and wait a year.And his father who had lived through the depression and kept telling him, "Be a plumber," his father said, "Don't do it. Don't take the money."
