Ego:

The ego, in Freudian psychoanalytic theory, is one of three parts of the psyche, with the id (instinctual desires) and the superego (morals and conscience). The ego acts as a mediator, processing information from the external world and balancing the id and the superego to make realistic, rational, and socially acceptable decisions,. It represents our physical and mental sense of self—our “I”—and our capacity for self-reflection and decision-making, often requiring us to delay gratification until appropriate. Ego can also refer to a person’s inflated sense of self-importance or self-centeredness. The ego develops as we grow, influenced by our experiences and interactions with the world. It can also be supported by defense mechanisms to manage anxiety and conflict arising from the id and superego, such as denial, repression, and rationalization.
