By integrating multidisciplinary findings from the science of high performance, Tony Schwartz makes a persuasive case that people are neglecting the four core needs that energize great performance - sustainability (physical); security (emotional); self-expression (mental); and significance (spiritual). Rather than running like computers at high speeds for long periods, people are at their best when they pulse rhythmically between expending and regularly renewing energy across each of our four needs. Drawing on extensive work with an range of organizations, among them Google, Ford, Sony, Ernst & Young, Shell, IBM, the Los Angeles Police Department, and the Cleveland Clinic, Schwartz creates a road map for a new way of working. At the individual level, he explains how we can build specific rituals into our daily schedules to balance intense effort with regular renewal; offset emotionally draining experiences with practices that fuel resilience; move between a narrow focus on urgent demands and more strategic, creative thinking; and balance a short-term focus on immediate results with a values-driven commitment to serving the greater good. At the organizational level, he outlines new policies, practices, and cultural messages that Schwartz’s client companies have adopted. The book offers individuals, leaders, and organizations a highly practical, proven set of strategies to better manage the relentlessly rising demands we all face in an increasingly complex world.
