Anyone that has tried to kick a habit knows how difficult it is to quit when the subconscious mind is an enemy. If your self-image is that you are a smoker then guess what it is going to be difficult to willpower your way out of that habit. Your brain doesn't want to make you into a liar. It believes that it is addicted--so it is.
that seems to follow the same logic: if your subconscious believes something, then it'll manifest in your actions...so what if you PR a "negative" book (anything that you find contrary to your beliefs/values/morals)? will your subconscious manifest the new negative information in your everyday life?
hmm....
