Depends on where you are located, but is there a community garden near you? I’ve lived in several cities and while most of my hobbies are pretty intense, gardening allows me to zen the fuck out and meet people outside of tech. Watching plants grow is such a tangible experience that I can’t get with software.
Someone else mentioned woodworking- that’s not my cup of coffee, but maker spaces are a great way to meet people and build something.
The last thing I can think of is your local library or community college- they may have courses for adults in a low pressure environment.
Godspeed :)
