Thoughts and words of Dr. John Hagelin PhD AB MA, Quantum Physicist from the movie "The Secret":

When we're positive - we attract more positive, when we're negative - we attract more negative

Our body is the product of our thoughts.  Science is starting to explore how our thoughts create and affect our bodies.  Within a few years we have a brand new body, cell-wise.  Negative thoughts have been shown to degrade our body.

We're using at most 5% of the human mind; imagine a world where everyone used their full mental and emotional potential.
