I thought this book was a sound choice for our third discussion, as it has remained highly regarded throughout the decades, being first published in 1937, during the Great Depression. Amazon states that over 100 million copies have been sold worldwide since it was first published. More than just a personal finance and/or personal development book, Think and Grow Rich focuses on philosophy and the power of the mind, with regards to wealth building. What follows is a summary of what I have learned from reading Think and Grow Rich.
