Emotional intelligence was originally coined in 1990 by psychologists Salovey and Mayer, and was popularized by Daniel Goleman in his 1995 book Emotional Intelligence. It can be defined as understanding one's own feelings, having empathy for others, and regulating emotions in a way that enhances living. There are four domains of emotional intelligence - self awareness, self management, social awareness, and relationship management. While IQ measures cognitive ability, EQ measures the ability to understand and manage emotions which can be developed over time and impacts performance, health, relationships and mental well-being. Developing emotional intelligence skills can help one succeed in life more than a high IQ alone.
