It's right there in Step 12, mellybug: Having had a spiritual awakening as the result of these Steps, we tried to carry this message to others, and to practice these principles in all our affairs.
Every so often a thread starts up where someone posts, just as you have done, about their recovery and how they see progress in areas that have nothing at all to do with the A in their life. One after another, folks will post about changes they are noticing, some huge and sweeping, others small and quiet, but ALL making a difference in the poster's life. "Practicing these principles in all our affairs" is a pretty great thing, w/some pretty great results.
Congrats on your progress!
