By Thomas Stanley and William Danko. The Millionaire Next Door Thomas Stanley and William Danko interviewed and surveyed a pool of millionaires, trying to find common connections to account for their success. They discovered that millionaires live below their means. They budget. They let their adult children make it on their own. And many millionaires are small-business owners. This is one of just a few books to cover both sides of the wealth equation: saving money and earning money. The bestselling The Millionaire Next Door identifies seven common traits that show up again and again among those who have accumulated wealth. Most of the truly wealthy in this country don't live in Beverly Hills or on Park Avenue-they live next door. Taylor Trade Publishing (2010), English, Paperback: 272 pages.
