Genius
For those who have never been to the top, they always wanted to reach the top.
For those who have been to the top, they all know how lonely it is to be at the top. That's why they never brag about being at the top.
A genius don't really understand that the common people cannot do what they can do. He have overly high expectations of others but he doesn't know it because he thought everyone else can do it. People claim that they don't have a good grasp on communication, but did they ever try to think that they are blinded by their own jealousy and unconsciously rejects them or even scheme against them?
A little more acceptance goes a long way.
