The Millionaire Next Door by Thomas Stanley

Thomas Stanley's The Millionaire Next Door shattered the flashy-wealth stereotype by revealing that 80% of millionaires are first-generation wealthy, living in ordinary neighborhoods and driving used cars. Based on surveys of over 1,000 millionaires, the book shows that frugality and self-employment are key, with the typical millionaire saving 20% of their income, far more than the average American's 5% rate. This research-driven approach is cheaper than the typical luxury lifestyle advice and provides concrete data on wealth-building habits. Compared to #7's 6-week program, Stanley's focus on long-term frugality offers a slower but more reliable path to seven-figure net worth.
