A key to mental fitness is to weaken the "Internal Saboteurs" that cause all your stress, anxiety, self-doubt, frustration, regret, shame, guilt, and unhappiness. In response to this phenomenon, Stanford and Yale faculty member, and prior Chairman of the Coaches Training Institute (CTI), Shirzad Chamine, created what he calls the Saboteur Assessment tool, and used it as the basis for his NY Times Best Selling book Positive Intelligence . Anu, a CTI coach herself, studied the Saboteur tool as part of Chirzad s Positive Intelligence Program, and it has since become one of her core coaching tools.
