All human activity can be viewed as an interplay between two contrary but equally essential factors -- vision and repetitive routine. Vision is the creative element in activity, whose presence ensures that over and above the settled conditions pressing down upon us from the past we still enjoy a margin of openness to the future, a freedom to discern more meaningful ends and to discover more efficient ways to achieve them.
