Vilfredo Pareto was an Italian Economist and Sociologist. Among other things, he derived something called the "Law of the Unequal Distribution of Results." You probably haven't heard of that. But you may have heard of the80/20Rule
That rule says that there are a small number of causes (say twenty percent) that account for most results (say eighty percent). In other words, some of the things you do give you more "bang for your buck."
