Emotional Intelligence is a foundational book introducing the concept of emotional intelligence (EQ) and arguing that emotional skills – such as self-awareness, managing emotions, motivation, empathy and social skills – play a vital role in personal and professional success, often as much as or even more than traditional IQ. Drawing on research in psychology, neuroscience and human behaviour, Daniel Goleman explains how people can develop these skills, why they matter in relationships, work and well-being, and how they affect the way we live, work and connect with others. The book helped make the term "emotional intelligence" part of global cultural and educational discourse.
