The document discusses how personal identity is shaped by various external influences throughout life. In particular, family has a strong influence during childhood as children tend to adopt their families' views. As people age, peers and media have a greater impact as they influence choices in clothing, music, language and more. Culture and religion also aim to keep people within certain boundaries and can influence traditional behaviors and values. Societal values come from different groups in a community and can represent laws, with people bonding over shared beliefs and values. However, conflicts can arise when individual or group values differ from those of society.
