Dr. Thomas J. Stanley (1944-2015) was the author of seven award winning books concentrating on America's wealthy population and was the foremost authority on the affluent. His last book, The Next Millionaire Next Door, was published posthumously in October 2018 and co-authored by Dr. Sarah Stanley Fallaw.
If The Millionaire Next Door was a look at what America's affluent look like, The Millionaire Mind is a look at how they think and live, and why. I liked TMND more, but this is a different kind of book. It more looks at habits and ways of thinking than simply at how people live. It also has a bit of a self-help vibe to it that detracts from the overall message of the book -- this can be overlooked, but does take away in the end.
Don't listen to the anti-wealth, anti-prosperity reviewers who give this book a negative review because they don't like the rich. Read it with an open mind and look at why the rich lead the lives with the habits that they do. One reviewer complains that the rich don't waste time and money on DIY projects but look to use discounting options like coupons. He totally misses that they do the latter because it is a good exercise in financial discipline that is primarily used to teach children (and that they understand thinking on the margin and the power of habits). Make sure you read the explanations!
I found this book absolutely fantastic. Thomas Stanley has obviously done a huge amount of background research in it's writing, and the information in the book is backed up by solid evidence from his findings.
This is one of the first ever books that I read on being a successful Entrepreneur, and I would recommend it to anybody with similar dreams!
