Why are Metrics Important?
Metrics are the units by which we measure success. We usually think of metrics in a business setting, but they apply to our personal lives too. Mark Manson does an excellent job describing how we use metrics to evaluate ourselves (warning: this Mark uses some NSFW language in this post). Examples of personal metrics an individual might value are monetary wealth, or for the altruistic souls, social impact. Examples of business metrics are profit margin and customer satisfaction score.
