In my sobriety I have found that one home group is better for me. Having just one helps me better to grow spiritually. It teaches me how to stick it out no matter what and continue to learn to build relationships, create teamwork and be a better team player (in and out of AA). It teaches me to practice love & tolerance, boundaries and be true to self; and, breaks down my self-contentedness, false pride, resentments, judgements etc.
I used to have several home groups but found that I just bounced around between them all. I'd get bored, fed up, whatever with one and stop going there for awhile and spent more time at the other "home groups" I had. Sometimes, I would find someone to take over my service position so I could take a break from the group. I've become aware how my Self-will (and more) can run riot having more than one home group.
So, now I have one home group but I have other meetings I'm really found of. I am in service at those other meetings by coming to them early and staying after to help set-up/greet/close-up and talk with newcomers and other members. I like the principle in the quote below too. Makes sense to me.
But doing service at more than one may deprive someone from having the opportunity to serve there themselves, in addition the AA literature does suggest one home group,
