Perception is how individuals organize sensory information to understand their environment. Emotional intelligence involves the ability to understand one's own and other people's emotions to guide thinking and actions. It has five components: self-awareness, managing emotions, self-motivation, empathy, and handling relationships. Emotional intelligence improves personal and professional lives. In personal life, it leads to better relationships, ability to accept change, and a happier life. In professional life, it allows for clearer thinking, better conflict resolution, managing job stress, better customer service, and improved job performance.
