Overview
The Pareto Principle, named after Italian economist Vilfredo Pareto, is a concept that suggests roughly 80% of outcomes result from 20% of causes. When applied to work, it means that approximately 20 percent of your efforts produce 80 percent of the results.
Application to Time Management
The Pareto principle in time management states that 80% of results will come from 20% of your effort. According to the rule, 80 percent of your daily work is accomplished in 20 percent of your day.
Origins
Vilfredo Pareto was an Italian economist who observed in 1896 that 80% of Italy's land was owned by 20% of the population. This observation has since been found to apply across countless domains, from business to personal productivity.
How to Apply the 80/20 Rule
Identify High-Impact Tasks
If you imagine you have ten tasks on your to-do list, the rule states that only two will account for and contribute to 80 percent of the results' total value. This means that completing a handful of high-impact tasks matters the most for reaching your goals.
Focus on the Vital Few
You dedicate your best focus time to 20% of the tasks that deliver the greatest or most important impact.
Minimize Low-Impact Work
According to the Pareto principle, 20% of all your distractions lead to 80% of your unproductive time, which is why you need to work on them.
