A framework developed by Shirzad Chamine to measure and improve the mind's ability to act as an ally rather than an enemy. Central to this system is the internal conflict between Saboteurs, which are destructive mental habits like the Judge and the Controller, and the Sage, which represents a person's inner wisdom and empathy. Chamine argues that while Saboteurs originate as childhood survival mechanisms, they eventually hinder adult success and happiness by generating unnecessary stress and anxiety. The sources outline three core strategies for growth: weakening Saboteurs, strengthening the Sage, and building PQ Brain muscles through brief mental exercises. Research and testimonials suggest that raising one's PQ score above a critical tipping point leads to higher performance, improved health, and greater fulfillment for both individuals and teams. Ultimately, the book serves as a guide for readers to reclaim control over their mental state and unlock their full potential.
