Focus on the vital few that produce most of your results

What is the Pareto Principle?

The Pareto Principle, also known as the 80/20 Rule, states that roughly 80% of effects come from 20% of causes. In productivity terms, this means that 80% of your results come from 20% of your efforts.

Origin

The principle is named after Italian economist Vilfredo Pareto, who observed in 1896 that 80% of Italy's land was owned by 20% of the population. This pattern has since been observed across countless domains.
