Theory of Mind

 http://en.wikipedia.org/wiki/Theory_of_mind  It is the idea that children cannot understand that other people have different ideas and feelings.  Basically, children believe the world revolves around them and they are they only thing that matter.  As we grow older, we develop the capacity for compassion.

Second level thinking can greatly improve relationships.  Relationships by definition is a two-way street.  If you can read body language well, or simply ask a friend questions from his perspective, it can go long way into developing a deeper relationship.  Most teenagers are unable to understand this concept, which may contribute to why high school is so harsh towards people who aren't "popular."  I also believe that I was able to form deeper relationships in college because of the slight increase in maturity. 

How do I get better talking to girls?  How can I interview better?  How can I be a better son?  How do I show my boss I deserve more responsibility?  We don't really need a book to tell us any of these things.  If we could fully understand the other person, we would have the solution to all of our questions.

Perhaps maturity and wisdom are both related to theory of mind and our ability to see through another's eyes.
