We are human beings, not human doings. ~ Anon
As humans, we have limits. There is just so much we can do and nothing more. We know that to be true when we hit that wall of fatigue and exhaustion. Those of us in service to AA recognize the need to stay in our own lane, do that which we can do and no more, and to share the load when it comes to AA service projects. Most healthy meetings know and practice the wisdom of sharing service responsibilities. Yes, chairs and literature need to be set out. Yes, someone needs to lead, make coffee, get supplies/medallions, represent the group at the intergroup level, be the contact/secretary/treasurer, etc.
How long should we do service work? According to tradition #8, it is customary that most group level jobs are for one year only. This keeps the work from becoming one person’s burden. It also helps the group stay strong, as new people will have a chance to do service, and there will be fresh eyes/minds that may bring new life into the situation. There is plenty to do. Invite new people into service work. Invite them to join you at intergroup meetings, and take them to retreats and workshops. The more they become involved in AA and have things to keep them responsible to their recovery community, the less time they will have to fight this dis-ease. Nice plan, right?
