I only have few topics to chat about

Mostly about university (I work there), but my family tells me that I shouldn’t talk about it a lot in family gatherings because no one cares about it, and the fact that I don’t know much else is obvious.

I used to be a better listener but for some reason I started to become more chatty. I hate this because I feel like I can’t control it sometimes.

My family used to tell me to talk more and this is the result: now I’m talking about uninteresting things to others, although I do well in work.

Any advice would be appreciated.
