How to anchor the hopeless case?

I've been reading up on and listening to lectures on NLP and some by Anthony Robbins and when they speak about anchoring they often talk about the person you are supposed to anchor finding a powerful moment or feeling in their life that you can anchor to a new situation. But what do you to help this person if he or she tells you they have never ever felt powerful in their life, that their whole life has been feeling victimised and helpless and no matter how much they wanted to take control of their lives they couldn't even imagine how that was supposed to feel? How can you anchor such a person? Won't you just be anchoring the bad feelings?
