Erik Weihenmayer's physical disability is blindness, but he still climbed Mount Everest with the help of his friends.  He also climbed El Capitan in Yosemite National Park.  Eric is the first blind person to climb the highest mountains on the seven continents.  He wouldn't have been able to climb the seven summits if he had a negative operating system running in his mind.  A negative operating system would have stopped him in his tracks.

Negative thinkers run a negative operating system, and the dark side of life controls their destiny.  They live a self-fulfilling prophecy that brings misery.  Their Bad Finders are up and running all the time.  When they look at their spouse, they list all of the shortcomings and failures.  When they look at their children, they focus on their dysfunctional teenage behavior.  When they look at their job, they see the threat of redundancy and recession.  When they look at themselves, they see stagnation.  The mathematics of negative thinking not only divides everything by zero, ending up less zero.  Negative thinkers keep track of all the negativity, and before long, they are less than zero.  They find themselves psychologically in the minus column with depression and dysfunction.

Positive beliefs are the only beliefs that take you to your dreams.  Negative beliefs take you to your nightmares, and running a negative operating system guarantees that you will torpedo your own future.  A negative operating system is a doomsday device that destroys your life; sooner or later your dreams will be blown to smithereens if a negative operating system is in control.
