Emotional intelligence (EI) is the ability to recognize, understand, manage, and influence emotions in oneself and others. It consists of five key components: self-awareness, which involves recognizing one’s emotions and their impact; self-regulation, which is about managing emotions and controlling impulses; motivation, which is the drive to achieve goals for personal satisfaction; empathy, which is understanding and responding to others' emotions; and social skills, which involve effective communication, conflict resolution, and relationship-building. High EI is linked to better relationships, leadership, mental health, and workplace success, and it can be developed through practices like mindfulness and active listening.
