What does it mean to turn inwards?

Turning inwards is an expression to know thyself. You can only know yourself when you understand your core beliefs, values that are pillars to your ego

When you turn inwards, you see your beliefs from a third-person viewpoint. To provide a filmmaking angle, you can see yourself as a hero in your own life’s movie, but not in his shoes per se, but as an audience. This encourages you to look at your story from a third-person perspective.

This would just make your life simple, balanced & purposeful.
