The two are independent, entirely different variables, meaning you can have one without the other. For example, maybe you know someone who is a complete navel-gazer with a high level of internal self-awareness. Yet you and everyone else think this person is a selfish jerk, but because he never receives external feedback, he has no idea. Conversely, someone could have a high level of external self-awareness, a clear understanding of how they fit in with the rest of the world, without knowing what they want and what makes them happy. To be truly, fully self-aware, though, you need both components — a feat that’s difficult to pull off for pretty much anyone. But, it’s worth noting, not impossible.
