Why is Freud's work on the Theory of Personality considered so important even by those who don't agree with him? What do you think about Freud?

I have come across Freud and his work several times and in different college courses. An interesting character, the majority of his work in psychoanalytic psychology is a reaction against the time period in which he found himself in, this time period being the Victorian era. So to truly take away from his work one must see what he brings to the table in an objective manner, or as objective as possible given that some of his ideas are a little radical even to our standards, for example his concept on psychosexual development. This concept roots developmental stages in sex and pleasure. One such stage and the first stage in his theory of development is the oral stage. During the oral stage, which takes place from birth till about 18 months, the infant finds pleasure in nursing making its mouth the erogenous zone. Strange, I know, but that’s not all that sets him apart. He also explores the libido, a basic psychic energy that can be compared to Chi or Parana. Chi is considered by most Eastern systems a vital energy that animates the body. Libido = Chi. Psychology defines libido as a psychic energy; Eastern Religion and the New Age define Chi as the flow of energy. Seemingly different fields of study with different terminology describing the same type of concept, a connection like that just shows you how interconnected our most valuable beliefs are. That is why Freud’s work on the Theory of Personality is considered so important. His ideas all connect to one another and to us. And the ones who don’t agree with him have the material he has helped collect which they can still use to create a more acceptable theory for themselves. Freud’s Theory of Personality is based on what drives us. Freud believes we are driven by sex and aggression, more formally known as Ethos and Thanatos. We are driven by these for simple reasons life and death. When we leave the house to go to school, or work, or just somewhere to hang out we make sure we look our best. Why is that? Simply, because if we look good it is more probable that we will attract a more suitable mate, hopefully, giving us the opportunity to procreate. To give life is one of the things that drive us to go on endless dates in search of Mr. or Ms. Right. Once we have the suitable mate, or maybe even before we find them, aggression will help us to protect the ones we have by our side or to stop the ones trying to meddle in our private affairs. In a nutshell, we are instinctually driven to survive. We are hardwired to live, procreate, and protect what is ours from those who wish to do us harm by attempting to or completely hindering these needs. Personally, I agree with this somewhat primitive and animalistic look into the human psyche.
