Consistently go to a group that is centered around an interest of yours. Consistency is key.

Use apps like meetup to find these groups.

If you're nerdy/geeky Aunt like computers and making stuff or 3D printing. I recommend looking in the maker spaces. There a lot of them around. They are communities where people can contribute what they have and people get together and make stuff and learn from each other.

If you're kinky, I recommend looking into local BDSM clubs. I find the crowds there tend to be very leftist.

Those aren't your speed. Maybe something more basic like a hiking group. Maybe there are salsa dance classes at a bar/cantina near you every week. Doesn't really matter what it is. Just find a group that's centered around something you like. Then attend that group regularly. Do that long enough you will make friends.

I hope that helps comrade 👈😎

Also remember most people suck so if you make a bad impression or piss some people off they were probably shitty people to begin with. Don't let it discourage you. 😊
