I like what Dr. Phil says, that there is no reality, only perception. We see what we WANT to see. This to me goes hand in hand with the whole power of positive thinking thing and the law of attraction. If you choose to see the world as bleak and hostile then that is what you will attract to you. I am living proof.
What about you? Do you subscribe to this viewpoint or do you think its all a bunch of psychobabble?
