I just read US News & World Report special issue on: Secrets of the Super Rich....which I highly recommend you pickup and read....let me share with you what it says on the back:

"The super rich are different from the rest of us- and not just because they have more money.  High-functioning and super competitive, they are known for favoring private jets, megayachts, and monumental mansions. But none of that is as important to most of then as pulling off a lucrative deal, creating a successful business, or inventing a new product or technology."

There is some amazing info that I learned about Rockefeller, Carnegie, Vanderbilt, Gates, Buffet, Walton, etc., and the stories/secrets of their success and philanthropy....this is a must read and is most likely also in libraries.....although for the $8 it costs, its pretty good to have around.
