Never forget `Pareto', you will find it applies to most of life. Quote> The Pareto principle (also known as the 80/20 rule, the law of the vital few and the principle of factor sparsity) states that for many outcomes, roughly 80% of consequences come from 20% of causes (the "vital few"). <End quote.

This is often misconstrued.

80% of sales come from 20% of the customers > yes, fire the customers who bring in 80% of the work.

80% of goals come from 20% of the players > no, your formation should not change everyone to forwards

Opportunities come 80% from networking, 20% from working hard > if you spend all your time networking, people would avoid you

Very often there's a support structure in place which leads to to the results.
