Emotional intelligence is twice as important as IQ in predicting career success. It involves self-awareness, self-management, social awareness, and relationship management. Leaders with high emotional intelligence know their strengths and weaknesses, manage their emotions well, read social situations effectively, and build strong relationships. Developing emotional intelligence is important for leadership success. While emotional intelligence is not fixed, it can be increased through self-reflection, getting feedback, practicing new behaviors, and building supportive relationships.
