AA members (Alcoholics Anonymous) or any addicted people are doing the opposite. They talk about drinking, they're celebrating round dates. I think the approach in the article is more effective for them.
In AA there is celebration around milestones (first days, then months then years of sobriety) and there is some discussion of past drinking. You'll often see a lot of both in movies, newcomer meetings or early treatment.
But substance abusers are selfish so a core function of working an aa program aside from trying to help others quit (objectively using ones own experience to help another) is actively taking inventory of past and present resentments, fears and selfishness to determine "what was/is your role in X?" and then making an amend to correct the wrong.
