Emotional intelligence (EI) is the ability to understand, manage, and express emotions effectively, both in oneself and in others. It plays a critical role in personal and professional success. Individuals with high EI are better at handling stress, building strong relationships, and resolving conflicts, as they can empathize with others and communicate clearly. In the workplace, emotional intelligence enhances **leadership**, **teamwork**, and **decision-making**, as it helps in understanding diverse perspectives. EI also contributes to mental health by fostering self-awareness, emotional regulation, and resilience. Developing emotional intelligence leads to improved well-being, stronger relationships, and greater life satisfaction.
