Yeah meeting new people isn’t easy once you’re out of school. If you are outgoing there are definitely avenues though. There are meetup groups for everything. You might not have hobbies, but you still do things. You bike? Go to the local riding meetup. You like boardgames? Sign up for your local open play at a boardgame store. You cook? Take a cooking class at a kitchen store or co-op. Anything you do, there is probably already a local group meeting up to do it.
