This digital collection, curated by Harvard Business Review, offers four books on the topic of emotional intelligence, found by bestselling author Daniel Goleman to be twice as important as other competencies in determining outstanding leadership. In Primal Leadership, With a New Preface by the Authors, the authors show that great leaders excel not just through skill and smarts, but by connecting with others using emotional intelligence competencies like empathy and self-awareness. The best leaders are “resonant” leaders—individuals who manage their own and others’ emotions in ways that drive success. In Resonant Leadership, Richard Boyatzis and Annie McKee provide an indispensable guide to overcoming the vicious cycle of stress, sacrifice, and dissonance that afflicts many leaders and offer a field-tested framework for creating the resonance that fuels great leadership. And in Becoming a Resonant Leader, Annie McKee, Richard Boyatzis, and Frances Johnston share vivid, real-life stories illuminating how people can develop emotional intelligence, build resonance, and renew themselves. Finally, HBR’s 10 Must Read on Emotional Intelligence presents 10 articles by experts in the field of emotional intelligence, all of which will inspire you to monitor and channel your moods and emotions; make smart, empathetic people decisions; manage conflict and regulate emotions within your team; react to tough situations with resilience; better understand your strengths, weaknesses, needs, values, and goals; and develop emotional agility.
