Dear Professor, The 80/20 principle is really an interesting one which created many a curiosity when introduced and was written first. Here's what Wikipedia has to say : " The principle was suggested by management thinker Joseph M. Juran. It was named after the Italian economist Vilfredo Pareto, who observed that 80% of income in Italy was received by 20% of the Italian population. The assumption is that most of the results in any situation are determined by a small number of causes " By the numbers it means that 80 percent of the outcomes come from 20 percent of our inputs. However, It really doesn’t matter what numbers we apply, the important thing to understand is that in our life there are certain activities we do (your 20 percent) that account for the majority (your 80 percent) of our happiness and outputs.
