I'm breathing a sigh of relief because I recently pared down from three communities to one. Now, before you get the wrong idea, two of them had zero members. Well, it's not exactly true… I was a member.
Something I've learned (and often ignore 🙄) is that having a sole focus is always better for my brain and focuses my creativity. Therefore, the one community I have that I'm dedicating all of my time to building is The Art of Living Solo.' I even wrote a brief book on the topic, and it's available as a free download in the community classroom. I'm starting a YouTube channel around it and also learning from on his excellent Skool Pinterest Skool to build interest in membership.
