I've spoken about community before. It's extremely important. It's one of the pillars in my Dominican family. It's very important in AA. We see exactly how important it is in my TOPS chapter. You just can't go it alone.
This was fact was brought home to me, again. We're reading Sacred Fire by Ronald Rolheiser. In chapter 5, pp. 137-139, Fr. Rolheiser tells several stories. They all point to "you can't do it alone." Community support is needed.
Whether you are trying to quit drinking, lose weight, or just become a better person, you need to join a support group. Learn to share, to help, and to love.
