I agree with the other definitions here.
When I first joined AA many months ago, I thought, "Ok, Step 1, sure I agree. Let's move on to the more important steps" but I didn't really agree deep down since I can choose not to drink, right?
It wasn't until I stopped attending AA after only three weeks and drank myself into oblivion the past 9 months that I can to a true understanding, and more importantly, a true acceptance of Step 1. If I had any "power" over alcohol, I would not be an alcoholic or have a drinking problem. Once I start I don't/can't stop, and once I finally accepted that, Step 2 became much easier, then Step 3. The program I once shunned I now embrace with open arms.
