This is a not bad strategy for gaining a bit more perspective about how we, as humans, intertwine our personal finances with learn and ingrained behaviors about money.
That being said, and with respect to what the authors are trying to accomplish—I assume it is enlightenment of personal financial problems and how to ‘re-wire’ our brains to overcome the bad behavior at the root of the issue(s)—the authors get very specific in their examples. Rather than discuss shortcoming from the lacking of a desired principle, some of the stories a bit over-specific.
One section that was enlightening, and that I can use with my clients, it the comfort zones. Also, very relatable is the either outgrowing, or not reaching the level of the family. I have had discussions with clients and they fall into one or both of these categories.
Where I believe they get too specific is in the financial genealogy. First off, as someone who enjoys genealogy and can name all eight of my great-grandparents, I am not sure I know enough of the money tendencies of anyone except my parents and father’s parents. This leave a bit too much for speculation. Now, this does not mean it is not a useful exercise, but may provide limited insight unless a close family relationship exists.
