Human intention in Health

I believe there is some aspect of believing for health to be achieved, and then again I do not think there has to be a belief..it just depends..I know people who just do not want to be healed or attain good health.  We, or others, get addicted to talking about our ailments and living with them.  So many do not even know what good health or state of being even feels like.  If they would start to attain it, what would that mean for them?  What dynamics would change in their life and what kind of choices would they actually have to start making?  Some of this is on a conscious level, but much of it is on a subconscious level.. But anywho, whether in eastern of western medicine, the intention of the person being worked on is a determinant to how quickly the person may recover..then again, maybe not!  Some may heal miraculously overnight, yet even what looks like overnight, may have taken much longer than we know..
