Something is missing in our lives. Australian Special Forces veteran and corporate psychologist Harry Moffitt has trained and worked with the best in the military, sport and corporate realms. He has seen up close what makes a champion tick, and what makes another squander the gifts they've been given. It comes down to purpose, self-awareness and the quality of our lived experience - it comes down to philosophy. In a world saturated by self-help, we all know the importance of the physical, psychological and social pillars of human performance. But as a society, we have forgotten the crucial fourth pillar - our philosophical self. The Fourth Pillar resurrects this critical ingredient of a life well lived, providing us with the tools to help navigate our anxious and uncertain world. By unpacking the ancient wisdom of the Stoics, the Spartans and beyond, coupled with hard-earned lessons from the battlefield and boardroom to sporting greats and NASA trailblazers, Moffitt reveals the path to true high performance, wisdom and fulfilment. Harness your potential and take back control.
