Identities are an important part of who we are and how we interact with the world. Egos and roles are two components of identity that help us to understand ourselves and our place in society. Egos refer to the individual self, or the sense of self-worth and self-esteem that we have. Roles refer to the social roles that we take on in our lives, such as student, parent, or employee. Together, egos and roles make up our identities, which shape our behavior and our relationships with others.
