How to I continue to try to find friends when most interactions I seem to be having are one sided.

That’s not to say that I don’t already have some people I interact with on a regular basis, it’s just that I’d like to expand that circle. I’m a bit awkward as I’m slightly socially inept. I know I gotta keep trying, but I need some new angles to work. How do I maintain interest in someone’s hobbies? Like not in doing them but show them that even though I’m not into what they are, that I enjoy very much that they enjoy it. It seems a lot of people can’t believe I enjoy hearing them just talk about what they like without liking it myself. Anyone have any tips?
