“We have seldom told them the whole truth nor have we followed their advice.” (Chapter 6, Big Book)
I don’t worry about changing my thinking in the sense of what thoughts occur to me. I concern myself instead with identifying which guide I decide to follow: (a) the ego (speaking through my voice) or (b) God (speaking through the programme, the principles, prayer / meditation, people I trust who are not invested in my life). Having identified the guide I to follow, I follow that guide regardless of what I think or feel.
