Some go to work on the great American novel. They need no preaching from us to find their way. True, there's always a few who stay bent over with head down after the sack is gone. We may try to nudge them, but it's their life. We don't sit in judgment.
Most people experience sobriety as liberation.
To be a part of that is reward enough. If we were to put sobriety in second place, behind some other goal such as uplifting the human character, we would soon get in a muddle. Sobriety has little to do with character. There are addict angels and sober scoundrels. Methods that may work for uplifting the human character may give little traction toward sobriety, and may even work against it.
