Most people consider themselves to be quite self-aware. But what if you could do it a little better—and get greater benefits from it in your life and career? There is compelling scientific evidence that people who know themselves and how others perceive them are happier, make smarter decisions, build better personal and professional relationships, and raise better children. This list can be continued for a long time. Self-awareness is a 21st century meta-skill. All of the qualities that are critical to success in today's world (emotional intelligence, empathy, influence, persuasion, communication and collaboration) stem from self-awareness. In other words, without self-awareness, it is almost impossible to master the skills that make us stronger team players, extraordinary leaders, and people capable of building stronger relationships both in the professional world and beyond.
