During early days in AA and in life in general I found myself doubting what others where saying. Things like I did the steps and had a spiritual wakening and the desire to drink was removed.
Quite often I heard people telling their stories and I was thinking to myself bull dust, I spoke to my sponsor about this and they said to me just because it is not my experience that does not mean it is not true. I used this simple statement several times afterwards and found that it was true. All of the time that I was thinking what the other person was saying was hog wash, the reality was it was not my experience.
By then accepting that OK what they are saying may be true but is not my experience also helped me to brake down some barriers in doing the steps initially and in challenging myself in general.
It has also helped me understand that if I want that experience then I have to do what they done.
