A ceramics teacher announced on opening day that he was dividing the class into two groups. All those on the left side would be graded solely on the quantity of work they produced, all those on the right solely on its quality. His procedure was simple: on the final day of class he would bring in his bathroom scales and weigh the work of the quantity group: 50 pounds of pots rated an A, 40 pounds a B, and so on. Those being graded on quality, however, needed to produce only one pot albeit a perfect one to get an A.
Well, at grading time a curious fact emerged: the highest quality works were all produced by the group being graded for quantity. The quantity group was busily churning out piles of work-and learning from their mistakes, while the quality group had sat theorizing about perfection, and in the end had little to show for their efforts.
Focus your efforts on building as much as possible, and you will keep getting closer to perfection without worrying about it. Don't waste time seeking the ultimate. Instead, focus your efforts on growing as much as possible, and keep moving forward.
