The core of Koch’s book is the Pareto Principle: 80% of effects come from 20% of causes. He takes this insight beyond economics, showing how it applies to time, productivity, relationships, and success. It's not a rule, but a pattern that repeats across life.

The 80/20 Principle is Rooted in the Pareto Principle

The 80/20 Rule is Universal

Strive for excellence in few things, rather than good performance in many.

Most of what we do has little impact. The key is to identify and focus on the small number of activities that yield the greatest results.

Focus on the Vital Few

Not all time is equally productive. Identifying your most effective hours and activities can drastically improve results.

Time is Not Equal

Powerful outcomes often stem from networks or systems that amplify effort. Build and optimize these to multiply your success.

Leverage Networks and Systems

The key to success is not hard work, but selective work—choosing the right things to do and doing them well.

Working smart beats working hard. Strategic thinking, reflection, and bold prioritization produce superior outcomes.

Redefine “Working Hard”

Effort and reward are not proportional. You don’t need to double your effort to double your results—in fact, often less effort can yield more if properly focused.

Success is Not Linear

Eliminating or reducing low-value activities can be more powerful than adding new ones. Simplification leads to clarity and better results.

Simplify for Efficiency

The 80/20 Principle isn't just for business—use it to enhance your happiness, relationships, health, and personal goals.

Apply the Principle Personally

In business, a small percentage of customers typically drive the majority of profits. Focus on serving and understanding them better.

Leverage High-Value Customers

Achievement is driven by insight and selective action—not by sweat, sacrifice, and suffering.

Identify which habits or routines lead to the greatest improvements and make those your focus—habitual excellence compounds over time.

Unlocking the power of focusing on the vital 20% for success.

Be more effective with less effort by learning how to identify and leverage the 80/20 principle: that 80 percent of all our results in business and in life stem from a mere 20 percent of our efforts. The 80/20 principle is one of the great secrets of highly effective people and organizations. Did you know, for example, that 20 percent of customers account for 80 percent of revenues? That 20 percent of our time accounts for 80 percent of the work we accomplish? The 80/20 Principle shows how we can achieve much more with much less effort, time, and resources, simply by identifying and focusing our efforts on the 20 percent that really counts. Although the 80/20 principle has long influenced today's business world, author Richard Koch reveals how the principle works and shows how we can use it in a systematic and practical way to vastly increase our effectiveness, and improve our careers and our companies. The unspoken corollary to the 80/20 principle is that little of what we spend our time on actually counts. But by concentrating on those things that do, we can unlock the enormous potential of the magic 20 percent, and transform our effectiveness in our jobs, our careers, our businesses, and our lives.
