Emotional Intelligence is "the subset of social intelligence that involves the ability to monitor one's own and others' feelings and emotions, to discriminate among them and to use this information to guide one's thinking and actions" ( Salovey and  Mayer 1990).
This means that our emotional intelligences is important because it affects we think and how we act as it helps people to interact with each other. Emotional intelligence is what we use to indicate how people are feeling and to control how we feel.
