Four forms of energy pulse through each of us at all times: physical, emotional, mental and spiritual. To thrive, we must recruit all four of these energies in the service of a specific mission. To be fully engaged means to be physically energized, emotially engaged, mentally focused, and spiritually vested. Jim Loehr and Tony Schwartz draw on 30 years of research and experience with thousands of world-class atheletes, FBI hostage rescue teams, emergency service workers, and corporate executives who must sustain high performance in the face of pressure. In this book they offer their precise understanding of how to help individuals and organizations manage energy to drive full engagement -- along with a step-by step programme to make that happen.
