I just completed my first step with my sponsor last night. I had a hard time with it. I wrote a lot of things down, but it was hard to stay focused. I don't know what my bottom was. I don't know why I was suddenly willing to go to AA, get a sponsor and work the steps when I couldn't bear the thought of AA even a week earlier.
Then I was at a meeting one night and afterward a woman said that her sponsor suggested she write, "The 10 Things I Never Thought I Would Do." In other words, things she did when drinking or because she wanted a drink that she never imagined she would do before things got so bad.
That made it easy. The first thing I wrote was about lying to people about how much I really drank. That started the ball rolling. A couple times it almost rolled right over me, but what the heck...my first step is done and I feel better.
Hope that helps anyone doing their first step work.
