The document discusses the concepts of actual self and ideal self. The actual self is who we currently are based on our self-knowledge gained from social interactions, while the ideal self is who we aspire to be based on role models and societal influences. There is constant negotiation between these two selves as we try to align our actual self with our ideal self through social roles and development. Greater alignment leads to well-being, while incongruence between the two selves causes mental distress. The goal of personal development is to increase self-knowledge and better align the actual and ideal selves.
