Based on research by Daniel Goleman, an influential American psychologist, author, and science journalist, emotional intelligence (EI) plays a key role in self-understanding. EI involves grasping your emotions, their impact on you and others, and using this insight for navigating life and relationships. It’s about tuning into your feelings and those of people around you, fostering personal growth and stronger connections. Essentially, mastering EI—staying calm, being emotionally aware, and building relationships—is crucial for a deep understanding of oneself.
