Emotional intelligence - the ability to accurately perceive, understand and manage our own emotions and those of others - is now embedded in our public discourse. It's an idea so pervasive and important in our society that leaders such as Jamie Dimon, CEO of JPMorgan Chase and New York City mayor Eric Adams have placed it at the heart of what they do. Daniel Goleman's bestselling book Emotional Intelligence was the first to coin the term and bring it to a mass audience. Now, more than 25 years after it was first published, he and Rutgers professor of psychology Cary Cherniss take a fresh look at how emotional intelligence has evolved. Reframing 'EI' as the foundation for performing at our best, they provide an essential guide for leaders and managers to: -Manage their emotions and negotiate those of colleagues, partners and friends-Increase concentration and encourage flow-Develop self-awareness-Build a sense of purpose-Harness empathy to influence and inspire Optimal shows how high performance can be cultivated at every level, scaling emotional intelligence from the outstanding individual to top teams and leading organisations in one definitive resource.
