Potential

I have no doubt whatever that 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...Much like the man who, out of his whole body organism, should get into a habit of using and moving only his little finger...We all have reservoirs of life to draw upon, of which we do not dream!

- William James (1842 - 1910)
