The 80/20 rule will change your business and your life. You don’t have to be an economist to be a believer. In the early 1900s, Italian economist Vilfredo Pareto observed that 80 percent of income in Italy was received by 20 percent of the Italian population. The rule simply states that, for many events, 80 percent of the effects come from 20 percent of the causes. The 80/20 rule applies to many things; for example, 80 percent of your sales come from 20 percent of your clients and 20 percent of the population has 80 percent of the wealth. The rule also applies to professional photographers. Only 20 percent of our business involves shooting photographs; the other 80 percent is spent running our business. Email,
