It can be hard if you don’t live in an urban center but even things like reading groups are a very simple way to meet people. Last time I did a book group I was surrounded by middle aged women that were just entirely enamored with a guy there that reads, the bar is very low honestly. With any hobby that involves interacting with others over a long period of time you will have a huge benefit from just not being a crummy person. With women especially there is a huge benefit from just being around enough to show that you aren’t a prick
