Rich Dad Poor Dad: What The Rich Teach Their Kids About Money That the Poor and Middle Class Do Not!
by Robert Kiyosaki, 1997

Maria and I listened to this on tape together. I think it’s a great introduction to using your creativity to build your personal wealth. Learn the difference between assets and liability (in both abstract and practical terms) and learn how to focus on building assets in your life. If you are interested in owning real estate, the author includes a lot of examples about wealth-generation through real estate.

Whether you read the book or not, I would suggest playing the Cashflow Classic game by the author. It can be played for free online here.
