Suggest a book that’ll help spark a genuine interest in talking to people / socialising

I’m bad at socialising. I think it’s also because I’ve been scared of people all my life (I have major social anxiety) that I don’t know now how to interact with them when the anxiety is less. One thing is I think I lack genuine interest in getting to know people maybe. My focus is always on what to say next to keep the conversation going rather than enjoying myself. What’s a book that’ll make me understand the importance / evoke a genuine interest in connecting with people? Could be fiction as well.
