Western and eastern philosophy believed that success and happiness comes in life if we handle our emotions and other's emotions too. The term "Emotional intelligence" was popularized as a result of Daniel Goleman's (1995) work. Although traditional understanding of intelligence is important for success in life, emotional intelligence is key to relating well to others and achieving goals, because the human world is all about relationships. We can say that by different measures as shown above one can observe oneself and feel comfortable to understand other's feelings, social-awareness and social disorder behavior even in adverse condition, better self-control, social decision making, etc. also can be brought positively and success ratio can be increased. Thus we can say that to be successful one requires to have effective awareness; control and management of one's own emotions; and awareness and understanding of other people.
