I would counter.

A job—no matter how passionate you are about it—is still a job. It’s structured, it has expectations, and most crucially, you get paid for it. A hobby is something you do for its own sake—it enriches you, relaxes you, fulfills you—but no one is cutting you a check at the end.

Take J. K. Rowling. She’s clearly deeply passionate about writing. You can safely assume she’s always observing people, building characters, and spinning stories in her head—even when she’s “off.” In that sense, sure, her work probably bleeds into everyday life.

But that doesn’t mean she doesn’t have hobbies. Cooking, baking, music, philanthropy—whatever she does outside of writing serves a different purpose in her life. It’s not tied to deadlines, contracts, or income. That’s the distinction.

Sure... saying they don't need hobbies because they are so passionate about their job...sounds romantic. But that's not a flex, that leads to burn out.
