"It is generally recognized that creativity requires leisure, an absence of rush, time for the mind and imagination to float and wander and roam, time for the individual to descend into the depths of his or her psyche, to be available to barely audible signals rustling for attention. Long periods of time may pass in which nothing seems to be happening. But we know that kind of space must be created if the mind is to leap out of its accustomed ruts, to part from the mechanical, the known, the familiar, the standard, and generate a leap into the new."
