Life is a self-fulfilling prophecy. You Get What You Expect.

Author Roger von Oech describes this phenomenon as the self-fulfilling prophecy, where a person believes something to be true which may or may not be so, acts on that belief, and by his actions causes the belief to become true. The self-fulfilling prophecy is a case where the world of thought overlaps with the world of action. And it happens in all avenues of life.
