Not really tbh. I don’t consider it to be about me. Just about anything can serve as a social object for people to connect over. It’s no more significant than happening to own a souvenir store next to a popular tourist attraction.
I think the reason Q’s like this don’t work for me is that they seem to assume an extremely constrained life.
I’m interested in MANY things, and one single book captures only one single facet. Even if I prioritize Physicist over all other identities, physics is BIG!
