Think about how great works are produced. As an example, imagine the studio of the great Italian Renaissance artist, Michelangelo Buonarroti, as he begins work on a sculpture. In the center of the studio is a huge block of pristine Carrara marble. Michelangelo positions his chisel and hits it with his hammer. Chips of stone break off and fall to the ground. Each day, for many days and months, chunks of expensive marble fall to the floor as his masterpiece slowly emerges.
