There is a line in the 12x12 that says "Having opened our channel as best we can..." (pg 102 step eleven)
This passage is referring to prayer and basically how to do it. I always want to point out "as best we can" and how important that is when going into step eleven. Years of sponsees reasoning if they can't do it right or perfect that they just won't do it at all has led me to use the phrase "as best we can" a lot.
We do step 4 to the best of our ability, we do not wait until our ability is better. We do the best we can on any given day and my experience is that "my best" fluctuates considerably. We need to learn to be OK with that. Our best does not mean our all time best record.
At work yesterday, I could not finish a single thing. I worked hard for nine hours, I did not goof off, I applied my self consistently but I still missed one of my deadlines. I drove off at the end of the day in peace because I knew in my heart that I gave my very best for that day. If my best is not good enough then that is out of my control.
Let's just do today, as best we can.
