This article discusses personality psychology research on reinventing oneself. It explores Gordon Allport's definition of personality as involving reflection on and striving to master one's environment. Allport believed people can function autonomously in new ways for new reasons. The article also examines Erik Erikson's life stage theory and how overcoming conflicts allows for reinventing oneself. Finally, it references research identifying three components - resilience, renewal, and reliance - that distinguish those who see aging positively and reinvent themselves from those who feel anxious about changes.
