The biggest complaint I seem to hear about from people is that there is too much stress in their lives.  Here's what Webster's dictionary defines as stress.

1.  A force exerted when one body or body part presses on, pulls on or pushes against another

2.  The deformation caused in a body by such a force

3.  A physical, chemical or emotional factor that causes bodily or mental tension and may be a factor in disease causation

Boy, I was.  If you're a spiritual seeker like I was for so many years, you may have tried everything!  I did.  I tried  and learned everything.  Before I could fully integrate one technique or process I was already learning or purchasing something new, the next greatest thing.  And I spent many thousands of dollars on all of this.
