The premise of The Pareto Principle, or the 80:20 Rule, is that for many outcomes, approximately 80% of the consequences will come from 20% of the causes. This is also know as the 'vital few'. On the other side of this - 20% of the consequences are the result of 80% of the causes.First observed by an Italian civil engineer, economist and sociologist Vilifredo Pareto in the early 20th Century, that 80% of the land in Italy was owned by 20% of the population. He further discovered that a similar distribution existed in other countries as well.Since then, studies have shown that the distribution of The 80:20 Rule applies in many other areas: in natural phenomena, business, health and productivity.It's a useful lens to assess and measure the results you are getting against the tasks and the effort you are putting in, in many areas of your life and business.What are the 20% of the activities that you are doing that are generating 80% of your results?And what are you doing for the other 80% of the time?
