Emotional intelligence involves the ability to perceive, assess and manage one's own emotions and the emotions of others. It was coined in 1990 and popularized in 1995 as involving abilities such as self-awareness, self-regulation, motivation, empathy and social skills. Emotional intelligence is not fixed and can be developed over one's lifetime through practice. It involves four main abilities - accurately perceiving emotions, using emotions to facilitate thinking, understanding emotional meanings, and managing emotions.
