How do you find friends where you have some commonalities?

The more I spend time with my friends, the more I realize we don't have much in common. I met them through a cultural association, which I'm not really part of anymore anyway. All they talk about is religion, dating, Beyonce, therapy, and nails. I find myself so restless and bored when I'm out with them. There's only so much you can say about these topics. They're all successful professionals, so I don't understand how they can have such limited interests outside of work. I just remember other times in my life when I found going out and socializing so much more fun and engaging.
