Article about Modest Young Millionaires

I read a book a while back called "The Millionaire Next Door". A couple of guys did a study of millionaires--what kinds of cars they drove, houses they lived in, if their parents were rich, how they made their money. It turns out that a lot of us live next door to millionaires and never know it, because they look just like "normal" people. They drive used cars, live in modest houses, and a lot of them are first generation-wealthy. Many of them are immigrants to the U.S. In short, they stayed out of debt and instead of putting their money into luxuries, they put their money into businesses or investments that MADE them money.

I read this article this morning about Modest 20-something millionaires. Our goal isn't necessarily to be millionaires, but we would like to retire well and not have to worry about money later in life
