The ability to express and control one's emotions is very important, including the understanding, interpretation, and responding to other people's emotions. The ability to understand and respond to the emotions psychologists call emotional intelligence, and some experts even suggest that it is more important than the intelligence quotient, especially in the business world. Through detailed and long-time research it has shown that people with higher emotional intelligence, as a rule, are much more successful than the person in whom these qualities are not developed. The concept of emotional intelligence gave rise to a lot of debates, and this is often a topic among scientists and practitioners of psychology. Most psychologists agree that traditional definitions of intelligence lack the inclusion of human abilities that are extremely important in the way in which we "intelligently" live our lives. And that the ability to know their own emotions, integration of emotions and thoughts, to understand emotions and to regulate emotions is important for the growth and development of the individual. Through discussions and literature, it has been shown that emotional intelligence is more important for business success than expertise and intelligence quotient.
