I feel that "doing" the steps is one thing, practicing them is a life long adventure. In my experience doing step 4 was an eye opener to my personal characteristics which were the reason I drank. To me it's a life long awakening of me and my feelings, fears, reactions, anger, resentments etc. Many still hang below the surface then appear, but are better handled now that I have the tools I was taught, sometimes reluctantly. It's also said that if a particular step is difficult, go back to the previous one, perhaps it's not completed. BE WELL
