Who are we? This question has disturbed human minds through countless generations. It's impossible to answer this question absolutely. Nevertheless, my intent is to describe human's characters as accurately as possible. I hope that the following explanations will serve for a better understanding of ourselves and what our real motives are, the way we act, think, feel, and why? The mind is an indivisible part of a human being. However, to describe the mind I divided it artificially into various components, as I do not know any better way to make the subject of the mind clear.
