Peta,
The one thing they teach in AVRT - and I'm not good at this myself yet - is that we shouldn't argue with our Beast or AV. Instead, you ignore it and stick to you Big Plan. To quote from Trimpey:
"Q: How long will you hear the Beast yammering and arguing and planning?
A: As long as it wants to yammer and argue and plan.
Q: Won’t constant AV destroy my happiness?
A: It’s like a baby crying for no reason; ignore it and it will get the message and quiet down.
Q: How can I reduce my AV?
A: Your fear of AV is AV itself. Let it be. It’s harmless, like a barking dog. No use barking back."
