"Most people live, whether physically, intellectually or morally, in a very restricted circle of their potential being.  They make use of a very small portion of their possible consciousness, and of their soul's resources in general, much like a man who out of his whole bodily organism, should get into a habit of using and moving only his little finger.  Great emergencies and crises show us how much greater our vital resources are than we are supposed."

~ William James (1842 - 1910), American psychologist, philosopher.

"Minds are like parachutes.  They only function when they are open."
