The main arguments for hypothesis about the role of emotional intelligence in human life are presented in the paper along with the review of empirical works concerning its relations with psychological well-being, health, social functioning and adjustment, school achievements, and job performance. Some data suggesting that excessive isolated emotional abilities may have an adverse impact are also mentioned.
