Emotional intelligence (EI) encompasses the ability to recognize and manage one's own emotions and the emotions of others, significantly impacting personal and professional success. While traditional education emphasizes IQ, EI is critical for effective interactions, emotional management, and achieving long-term happiness, with research suggesting it accounts for 80% of success. EI can be developed at any stage of life, contrasting with the largely static nature of IQ, highlighting the importance of cultivating emotional skills in both personal and professional contexts.
