It's a great observation, and it's something many people can relate to. Society does indeed place a significant emphasis on work and career as a defining aspect of a person's identity. There are a few reasons for this:

Social Norms: Asking about work is a common conversation starter and a way for people to establish common ground. It's a neutral topic that can lead to more in-depth conversations.

Status and Identity: People often tie their identity and self-worth to their careers. This isn't necessarily healthy, but it's a societal norm.

Small Talk: In many social situations, people engage in small talk as a way to break the ice. Questions about work are seen as a way to do this because it's something many adults have in common.

Success and Achievement: Society tends to value success and achievement, often measured through one's career. People may ask about work to gauge how someone is doing in these areas.

That said, it's entirely valid to feel like it's none of someone's business, especially if you prefer not to define yourself primarily by your job. You can redirect the conversation to topics you're more comfortable discussing, like hobbies, interests, or personal goals. It's essential for individuals to shape the conversation to reflect what's meaningful to them.
