Sigmund's famous Personality theory involves three different stages. These are all part of what we call the structural model. It is composed of the id, ego and superego.
From the moment we were born, the id is already a part of us. This personality prioritizes the goal of meeting your needs no matter what. It only focuses on itself and its own pleasure. That is why babies are very sensitive and moody when they are not properly cared for. As we grow, we develop the ego personality. At this stage, people are more understanding and complacent. They still try to pursue their pleasures but only if it does not hurt or violate other people's welfare. In the mature stages of our life, we develop the superego. This personality is hinged on the moral principles and beliefs of a person. We develop a sense of conscience.
