Answer:
The answer is: the 80/20 rule
Explanation:
Applied in business, the 80/20 rule (also called the Pareto Principle), states that 20% of your customers account for 80% of your sales. It doesn´t necessarily need to be an exact proportion of 80/20, but as a rule it should help organize our time and activities in dealing with our most important customers.
As a general rule it applies to most activities of a person´s ordinary life, were 20% of the time we spend result in 80% of the benefits.
