Pareto’s Law 80/20 means that in anything a few 20% are vital in the many 80% of trivial
a small number of causes, 20% account for 80% of the results
20% of the people had 80% of the wealth
20% of the defects caused 80% of the problems
20% of the work in some 80% of your time and resources
20% of what you do produces 80% of the results
