Emotional intelligence involves the ability to monitor one's own emotions and understand how others feel in order to guide thinking and behavior. It can be developed in five major areas: self-awareness, managing emotions, self-motivation, empathy, and handling relationships. Becoming emotionally intelligent is an ongoing journey that starts with understanding one's own feelings without blaming others, setting goals using positive emotions, and overcoming blocks like prejudice, low self-esteem, and oversentimentality. The ultimate goal is achieving harmony.
