So think about this. When you initially started DBing, did you have no expectations? Were you doing the work because you knew it was important for you, regardless of whether your M would be saved? Or, were you doing the work in order to save the M?
IOW, if you don't think you would have done any of the DB work had you known that it wouldn't save the M, would you have done it?
I don't want you to answer "yes" to that question. I don't want you to say that you would have done this work, regardless.
Because the harsh truth is, most LBS probably would not have done any work on themselves...
except... that they found themselves in this position and became desperate to save their M. And, so did the DBing only to save their M.
Are you prepared to start from square one? Now without expectations of saving your M or trying to control the outcome?
