" Focus and simplicity…once you get there, you can move mountains.” Steve Jobs
The 80/20 Principle, also known as the Pareto Principle, is a very basic yet powerful concept in business optimization and decision-making. It states that roughly 80% of outcomes come from just 20% of causes (could be 90/10, 70/30 or some variant)
This uneven distribution appears across industries, systems, and even personal productivity—revealing that a small number of inputs often drive the majority of results.
Originally observed by Italian economist Vilfredo Pareto in the late 19th century—who noted that 80% of Italy’s land was owned by 20% of its population—the principle was later popularized in quality management by Joseph Juran, who coined the terms “vital few” and “trivial many.”
The 80/20 Principle helps organizations:
Focus on the Vital Few. Let Go of the Trivial Many.
The Pareto Principle in Personal Life
The Pareto Principle also applies far beyond economics—into how we live, work, and make decisions.
In personal life, it means that a small portion of your habits, relationships, or routines likely drive the majority of your fulfillment, productivity, or stress. The key is identifying those “vital few” and optimizing around them.
