My number one advice is, if you enjoy it, to play board games. I've met people of all ages and most board gamers are very friendly. There's a wide selection of social games, or if you're similar to me, the more "thinky" strategic games, where there is less talk during the game but some good discussions afterward.

It's easy to reach out to others and say, "hey, how about a game?" because it's sets expectations with others, and there are plenty of cafes to offer neutral meeting spots.

It can be a slow process to build a social hub around it, but the key is regularity and common interest. Could this be applied to other hobbies? Yes!

My fallback would be bridge playing groups, knitting, or woodworking groups. No book clubs, I haven't had good experience with those.
