I've longed for a secular "church". A place to gather with the community on Sunday to listen to a non-religious sermon (the importance of self-control and techniques to help; the role emotions play in our lives, what they are, where they come from, and how to manage them), form smaller interest groups, and connect with people in the area. I believe The School of Life [0] tried this in London but I don't see any mention of it on their website today.
I've had luck with sports, specifically cycling. Check out Strava for groups in your area and just show up to a ride and introduce yourself.
