O is for Open Mind. I was thinking mine wasn't very open, I realized it would be just much easier, just to add to each letter each week, instead of starting a new letter each trying to remember a new word or concept.
Recovery is discipline, but I don't think we should limit ourselves either and we need to be open to new things and we need to stretch our boundaries.
As I have said before, "Don't keep such an open mind that everything falls out of it," but don't keep it so closed that nothing new can come in and refresh your soul.
