Why does someone have to have the same interests in you? Ask them questions and find out why their interests are different. You can often learn more from a person with a different perspective. Escaping the echo chamber is hard but very rewarding.
90% of the time I get out of this echo chamber I find myself trapped in discussing the last episode of X TV series or Y sports match. I'm fine with that, but sometimes I'd prefer to talk about other stuff and finding the right people blindly can be hard.
