Why Is It So Important to Be Aware of the Ups and Downs of the Stock Market?

When i read wheeler's book, and again, i'll throw yours in there as well, my big insight was, this is not just for manufacturing. This is not just about getting the specifications right for a certain product. This applies in measures, metrics, capios, whatever you want to call them. And we can sometimes fool ourselves or mislead others when we start trying to ascribe wins and losses just based on one or two data points. So whether it's crime data, economic data or ta winning percentage of a sports team over time, a business measures tend to just fluctuate around an average.
