It comes from treatment centers. They charge $12k to tell you a plethora of things that aren't in the book or the AA program. They then give you a book and send you to AA armed with this wisdom and knowledge. Hence, AA is full of these disinformation warriors that never took the steps, lived the program or even know what the book says. They therefore sit around and invent things to say.
Nowhere, anywhere in the book, the steps or traditions does it say anything about putting any aspect of your life on hold. Ever! Remember, we put our will and our lives into the care of God as we understood God. So do we tell God that the will of the disinformation warriors supersedes his will and the people he put in your life will just have to wait for a year? It's no wonder people are walking out the door by the droves.
