According to Holland's theory, how does a person's job affect their self-definition?

According to Holland's theory, a person's job plays a significant role in shaping their self-definition because it provides a means through which individuals express their interests, values, and personality traits. Holland emphasizes the concept of "congruence," which refers to the fit between a person's characteristics and their work environment. When individuals work in an environment that aligns with their inherent personality types—such as realistic, investigative, artistic, social, enterprising, or conventional—they are more likely to experience job satisfaction and view their work as an extension of who they are.

In this context, a job becomes much more than just a source of income; it is intertwined with an individual’s identity and self-concept. By engaging in work that resonates with their core traits and inclinations, individuals can derive a sense of purpose and fulfillment, thereby enhancing their self-definition and overall well-being. This connection between work and identity is central to Holland's model and underscores the importance of aligning one's career choices with personal identity.
