Hey Candy,
The compact, in a nutshell, answer is that I really believe trying to help other alcoholics get sober keeps me sober and I feel a real desire (obligation?) to help at least one other person find what I found. Also, and this is the hokey sounding, Miss America contestant part of the answer, I believe that people who cross the bridge into recovery are different and that each person who finds their way makes the world just a tiny bit better.
