A 30-year-old individual feels a sense of confusion about their career choices and personal relationships. They are unsure about their identity and often compare themselves to peers who seem more successful. According to Erikson's theory, which stage are they likely struggling with, and what challenge does it present?

According to Erikson's theory, the individual is likely struggling with the stage called "Identity vs. Role Confusion," which typically occurs during adolescence and young adulthood. In this stage, people work to establish a clear sense of self and their place in the world, including their career and personal relationships. The confusion they feel about their identity and the tendency to compare themselves to more successful peers show that they are unsure about who they are and what they want from life. For example, if they see friends advancing in their careers, they might question their own choices and feel inadequate.
