There is no physical body, no matter what the conditions, that cannot achieve an improved condition. Nothing else in your experience responds as quickly as your own physical body to your patterns of thought.
Esther Hicks..... if we were talking to you on your first day of physical life experience, we would say to you, "Welcome to Planet Earth. There is nothing that you cannot be, or do, or have. You are a magnificent creator. And you are here by your powerful and deliberate wanting to be here. Go forth, giving thought to what you are wanting, attracting life experience to help you decide what you want and once you have decided, giving thought only unto that"
