A famous psychologist, Albert Ellis perhaps, had the opinion that you could loosely gauge the depth of a person's identity if in the first ten minutes of newly meeting them the topic of occupation never arises.

Sometimes I play that test on people I meet. My experience has been that very few people resist introducing themselves apart from what they do (or have done) for a living. Neither good nor bad, just telling of what we first think of when we consider who we are.
