One thing????
Well being 55 I have had a few things that changed me as a person! LOL
1. My dad passing when I was 19.
2. The births of my first 3 children.
3. Joining the Air Force.
4. My first wife deciding after 17 years of marriage and 3 kids that (In this order) that she no longer wanted to be a mother or a wife any longer.
5. Meeting my present wife.
6. The birth of my twins.
7. Standing on the edge of a cliff knowing that if I continued to drink I would go over the edge and all of the above would have meant nothing.
8. Going into detox.
9. Going to AA and actually gaining HOPE for the first time in many years that even an old drunk like me stood a chance at staying sober.
10. Taking the steps with my sponsor and having a spiritual awakening as a result of them.
11. Passing on to others what was so freely passed on to me.
12. Living a life beyond my wildest dreams (Not materially) and being able to enjoy all of the above one day at a time.
9 thru 12 are the biggest deals in my life, without them my 8 grand children would never have known me as a grandfather.
