Humanity and Emotion

What is life composed of? This is a question that I have asked myself sometimes, because I really want to figure out life. I want to figure out what human beings really are, and how we interact. So this post is about one of my thoughts on this subject.

Everybody has emotions. And occasionally these emotions get the better of us. There is certainly more to life than this, but this is a major part of what influences actions as a people.
We feel joy. We feel sadness. We feel frustration, excitement, depression, hope, despondency, affection.
Because we all feel these things, we are all able to understand when others feel this, if we try. The problem is, on most occasions, people are too wrapped up in their own emotions to see things as they really are.
As we understand these emotions, we can learn to more effectively deal with people. And we can better try to understand ourselves and learn how to be better people, who know how to control ourselves.
