I've found that it takes practice and patience to change old habits, attitudes and thoughts.
Truly accepting my powerlessnes is something I need to concentrate on consistently throughout my day.
At times I can find myself slipping backwards in this regard, most often with situations that have nothing to do with addiction, alcoholism or anyone _else's_ ism.
Yes, I am powerless in many (most) ways but I am not powerless over my choices about myself, and when it comes time to change and allow what I've learned to seep into all aspects of my life: It's good.
