Reddit is full of "I stay home all the time but find it hard to meet people, why is that?"

You gotta get out to places where people might actually be. Look for clubs or other activity groups in your area.

I like board gaming. Back when I traveled a lot for work I'd search the city I was in to find their local board gaming group. 70% or better of the cities I went to had one that was meeting when I was there. Usually in a restaurant or library. Meet up, play some games, meet some people, it was fun. I made some friends who I've kept up with for years now.

Volunteering is a good way to meet people too, the library is always looking for volunteers.

Join a charitable organization. A friend of mine is in the Lions club, they raise money for lots of different charities. I helped with one of their fund raisers and met a whole bunch of people. It can be a good way to meet folks in your town...
