(21 m) I want to get rid of my Superiority Complex but don't know how

I'm not a show off by any means but I consider almost all the people I meet shallow or just plain ignorant. It's really made it difficult for me to even wanna try to socialize with new people since I mostly consider them uneducated people who mostly care about stuff I don't consider important like gossip, partying all the time, sex etc.

Does anybody know some good sources, books or sites that can help me understand myself more? Or offer tips you know from experience or knowledge if you have them Thank you
