Emotional intelligence involves the ability to monitor one's own emotions and others' emotions to guide thinking and actions. It is comprised of five domains: self-awareness, managing emotions, motivating oneself, empathy, and handling relationships. Success in any field depends on understanding and managing emotions in oneself and others. A high level of emotional intelligence provides competitive advantage and allows one to perform at their best and bring out the best in others. Extraordinary levels of success cannot be achieved without a high level of emotional intelligence.
