If we could get your subconscious mind to agree with your conscious mind about being happy, that’s when your positive thoughts work.
More Bruce Lipton quotes :
Our thoughts are mainly controlled by our subconscious, which is largely formed before the age of 6, and you cannot change the subconscious mind by just thinking about it. That's why the power of positive thinking will not work for most people. The subconscious mind is like a tape player. Until you change the tape, it will not change.Bruce Lipton
