Yesterday, during a discussion about great books written on the subject of money, I had a wonderful flood of memories surrounding the time I first read (circa 2001) The Millionaire Next Door / Summary. 

Automatic must read.  This book has always stayed with me because it shattered my naive view of "all hat and no cattle" millionaires and how net worth millionaires function.  A fundamental shift for me about the identity of money.

What book(s) would you recommend?
