Get over yourself.
I had to learn to get over myself.
Accept your fear of being judged and open your mouth anyway.
I had to open my mouth in AA meetings regardless of how sure I was that everyone would think I was stupid or vain or too sick or not sick enough or good or bad or whatever I was that I shouldn't be or wasn't that I should be. I had to open my mouth and share in AA meetings to smash through my fear of judgment. And I had to do it more than once for it to be thoroughly smashed.
Because the medicine in a meeting is transmitted through the process of identification.
If I don't share, I am potentially withholding help from someone else.
It is not vain to consider the idea that what you share might help someone. It is accepting that you don't know everything. (Stop playing God!)
I share in meetings because that is one key way to "carry the message to other alcoholics." In other words, that is one key way I can practice the 12th Step.
I need meetings because it is in an AA meeting I can take my turn carrying the message.
I need meetings because it is in an AA meeting I might help someone else -- even if they never tell me or I never know it, I participate in case I might.
I need meetings to help me live the 12th Step.
