I'm an introvert. I'm also a remote worker, and I no longer attend church. I was very involved in the church when I was growing up, so I'm well aware that my life is now lacking something, in terms of connection and a sense of community.
I've recently been searching for some alternatives. There's Unitarian Universalists [1], who welcomes people from any faith, including atheists and agnostics. You can discuss any religion openly, and they have regular services on Sunday where you can socialize, enjoy some music, and listen to a speaker.
There's also the Rotary Club [2], where people regularly meet for meals, and work to help their community. Then there's the Freemasons, but I don't think that's for me.
I might like to organize a secular humanist "church" or club with regular meetings and meals. I think it would be nice to have discussions about philosophy and science, maybe watch some documentaries and talks together, and have a book club.
Another random thought on the topic of isolation: St. John's runs a "caring caller" [3] service in New Zealand, where people can volunteer to call elderly people on the phone, and just have conversations with them. If I'm ever back in New Zealand, I think I would like to get involved with that.
Also in New Zealand: The High Street Cohousing project [4] in Dunedin. I think it's a fantastic idea. I love the idea of a shared community space, and the sustainability. I'm seriously thinking about getting involved, or maybe I can buy one of the houses in the future.
I enjoy living in Chiang Mai, and it's not too hard to meet people here. There are plenty of meetups and groups to join. I meet a lot of digital nomads who come and go, but my wife and I have a small group of friends that are living here long term. There's also a Rotary Club here that we have been thinking about joining.
My wife and I have also been rewatching Gilmore Girls. We agree that it would be really nice to live somewhere like their fictional town of Stars Hollow, in Connecticut. The main reason is to be part of a close-knit community, but also because that area has distinct seasons (especially fall and winter), beautiful architecture, history, and close proximity to New York. I ended up reading quite a lot of articles and blog posts from people who want the same thing, and have visited similar towns in Connecticut. One blog post was a bit depressing [5]. They are saying that this town could never exist, because of big-box stores like Walmart who are killing many small businesses.
YC has a plan to build a new city, so I hope they are thinking about these things. I think the issues of community and isolation might be more important than anything else.
