The Millionaire Next Door by Thomas J. Stanley & William D. Danko Ph.D. (paperback)(E)

This finance/self-help book is based on a long-term study of millionaires in the U.S. It reveals that many wealthy people don’t live luxurious lives: instead, they accumulate wealth through frugality, disciplined saving, smart investment, and avoiding conspicuous consumption. The authors contrast “Prodigious Accumulators of Wealth” (PAWs) with “Under Accumulators of Wealth” (UAWs), showing how behavior, habits, mindset and lifestyle choices are more important than high income when it comes to becoming truly wealthy.
