this is going to sound like lame, unsatisfying advice, but in my experience, it seems that my friends find me more often than i find them.
just be yourself, and you'll inevitably find like-minded people who share your interests. it might take a while, though.
i will concede that finding friends irl feels like a very hopeless endeavor these days if you're not currently in school, though. hangout spots are nonexistent, and even if you live in an area that has several, it's unlikely anyone that isn't elderly is just hanging out, much less anyone you might have anything in common with. i would maybe suggest going to a convention or something (assuming you're the type of the person who's interested in things that have conventions lol) but even then it's kind of a costly endeavor.
