5. The Millionaire Next Door by Thomas Stanley and William Danko

Some personal finance books promise to show the reader how to become a millionaire. The Millionaire Next Door (by Thomas J. Stanley and William D. Danko) is different.

This is a subtle but important difference, and more then 2 million copies sold and three years on the New York Times bestseller list can’t be wrong. Buy The Millionaire Next Door Conclusion
