Emotional intelligence refers to the ability to recognize one's own feelings and the emotions of other people, to motivate oneself, and manage emotions and relationships well. Therefore, it differs from academic intelligence which is measured by intelligence quotient, but their abilities are complementary. The more complex the occupation, the more important emotional intelligence is because the lack of these capabilities can diminish the technical knowledge and intellect that the employee has at his disposal. Some of the most important abilities that are needed in a business environment are self-confidence, self-control, empathy, communication skills, problem solving, organizational effectiveness, people management and teamwork. In order to recognize and develop these abilities,an individual needs to develop self-awareness first – to know his/her „self“. It is necessary for him/her to know his/her attitude towards changes, learning styles, values and emotions in order to get a complete self-picture. Furthermore, it is important to control emotions as they usually lead to one's behavior and reactions, and this skill is significant in uncertain situations when stress occurs. Also, by recognizing one's own and others' emotions, an individual becomes adept at communicating and active listening which is a significant prerequisite for teamwork and people management. When each member does their best the results can be multiplied, and the collective level of emotional intelligence increases. Empirical research in this paper has shown that entrepreneurs highly value the expansion of business friendship networks because it, in addition to increasing productivity and efficiency of the individual, creates an emotional connection that can affect the improvement of human capital and realize the successful goals of the organization.
