I'll also call BS on the 90/90 thing. If it works and fits into your life then do it. If it doesn't, then don't do it.
The day that Sobriety and A.A. becomes a burden or becomes something I feel forced to do, I'll probably end up drunk. I'm supposed to be enjoying sobriety. Aren't I?
The 90/90 thing that I don't get is, how the hell can we plan a 90/90. Isn't that thinking three months into the future when we are supposed to concern ourselves with "Today" and not "Tomorrow" per the suggested program?
