Why Emotional Intelligence is the Real X-Factor in Success

In a world that prizes IQ, technical expertise, and hustle, On Emotional Intelligence makes a compelling case that the true differentiator in leadership, career growth, and personal fulfillment is how you manage yourself and relate to others.

Published as part of Harvard Business Review’s 10 Must Reads series, this volume distills the most influential research and case studies on Emotional Intelligence (EI) from thought leaders like Daniel Goleman, Annie McKee, and Richard Boyatzis. Rather than treating EI as a “soft skill,” the book positions it as a hard-edged, measurable driver of performance that influences decision-making, collaboration, resilience, and influence.

The message is clear: mastering Emotional Intelligence isn’t optional it’s the foundation of exceptional leadership and sustainable success.
