Daniel Goleman is an American psychologist who wrote the book Emotional Intelligence. The book has sold over 5 million copies and has been translated into 40 languages. It has been on the New York Times Best Seller list for over a year. Goleman's book focuses on the idea of emotional intelligence, or the ability to perceive, understand, and manage emotions. This can be applied in many areas of life, from relationships to work to health and fitness. Goleman's research has shown that emotional intelligence is a better predictor of success than IQ. This is because IQ only measures cognitive ability, while emotional intelligence takes into account things like self-awareness, empathy, and self-regulation. One of the benefits of emotional intelligence is that it can help you to better manage your own emotions. This can lead to improved mental and physical health, as well as better relationships and work performance. If you're looking to improve your emotional intelligence, Daniel Goleman's books are a great place to start.
