You get to see love, hate, fear, rage, happiness. You get to hear caring, sadness, anger, friendship. Most of all, you get to experience minds of all kinds. When I heard that, it helped me better understand myself.
Most people look outside themselves for things they already possess within.
Although, in most cases people talk of their achievements to gain acceptance, or props, or whatever. What stands out to me are actions. Talk is cheap. If a person has good intentions and realizes they are not the center of the universe, but instead that they are a part of it, then they are a valuable friend. My friends are special to me.
