A finance guru friend suggested this book to me because I have a moderate fascination with personal finance - especially after the Great Recession. It was written in 1996 and it was written specifically for 40 to 60 year olds, so you have to keep this in mind while you are reading it. But it does present some potentially life changing information about how average people become rich and why most people who look wealthy are actually quite poor (the book uses the analogy "big hat, no cattle"). It's worth a read whether you're concerned with money and your personal finances or not.
