When I lived in New York City, I knew an awful lot of Scrooge McDuck millionaires. Just all wrapped up in the chase for money, self-absorbed, and not very interesting people.
On the other hand, I went into business with a couple of people who were just the nicest folks and the most interesting folks I ever met. They were a man and woman, cousins. We had a really good time together running a stressful business, and we made a decent amount of money. I learned months after I met them that both of them were millionaires by birth. I never would have guessed!
