I felt like it focused too much on outliers to be really helpful. Just because those strategies worked for the teeny tiny percentage of people who became very rich doesn't mean they will work for the vast majority of regular people.
EDIT: Never mind, thought you were talking about Secrets of the Millionaire Mind by T. Harv Eker, not The Millionaire Mind by Thomas J. Stanley. Only read TMND by him, not TMM.
