i don't know how to meet people with similar interests

Events! Events are a great way to meet like minded people or people with simalar intrests, depending on the norms with in some groups you might aswell also meet peopel who spend mos of their time online. 

Conventions are great, there are so many difrent types of cons, there are cons for shows, hobbies, companys and  so much more. There is even cons for like farmers i think??? so like there is most likely one you would have atleast some intrest in!

I cant speak to how you would form a conecktion there my self as I have yet to be able to attend one but friends of mine has meet friends and people who well became or might  become more then friend there :)

There is a group of people in my town that hosts table top role play games some week ends every third month or so wich is were I get to meet new people and some times form a conection that lasts outside the event.

I don't really know much about that either, but I heard you should go to the social things that involve the things you're interested in.

For example, I enjoy martial arts, so I should sign up for a membership at the local martial arts gym to learn Jiu Jitsu. I have actually done this for a short while and I got to interact with lots of people interested in martial arts. I even met and rolled with a very beautiful young woman that I could have possibly gotten to know and talk to and eventually develop some sort of relationship with like friendship or maybe more idk.

So I guess you just gotta get out and do fun stuff and talk to people. That's the best I got.

Definitely just going to cons or events in your nearby area, like the other person said

Participate in community events where you organize or through socializing while playing Geometry Dash Lite so you can easily start conversations with others and have the same topic to talk about.
