Shoemaker, stick to thy last! . . . better do one thing supremely well than many badly. That is the central theme of this Tradition [Five]. Around it our Society gathers in unity.

The survival of A.A. depends upon unity. What would happen if a group decided to become an employment agency, a treatment center or a social service agency?

Conformity to A.A.s primary purpose insures the safety of the wonderful gift of sobriety, so my responsibility is enormous. The life of millions of alcoholics is closely tied to my competence in carrying the message to the still-suffering alcoholic.
