I found this to be far more insightful than I honestly thought it would be, both in relation to my own behaviours and those of others, some of the descriptions certainly brought various people to mind s well as a few 'that's exactly it!' moments. As well as that, I did find a few of the hints and tips throughout the book intriguing and I'm certainly going to be reading back through and noting those that I think will help (although I will not be dog-earing the pages!). Granted the 4 main personality groups may be a simplification, one that Erikson fully acknowledges and reminds the reader of throughout, but it is certainly a good starting point for understanding yourself and others in different roles, especially if, like me, you haven't read much around the subject.
