One example from the book that supports the main idea of the 80/20 Principle is Koch’s discussion of the Italian economist Vilfredo Pareto, who first observed the principle in action. Pareto noticed that 80% of the land in Italy was owned by just 20% of the population. He also found that 80% of the peas in his garden came from just 20% of the pea pods. Koch uses this example to illustrate how the 80/20 Principle can be seen in many different areas of life, from wealth distribution to productivity.
Another example Koch gives is the application of the 80/20 Principle in business. He argues that businesses should focus on the 20% of their customers who generate 80% of their revenue, rather than trying to please everyone. He cites the example of Amazon, which initially focused on selling books to a niche market of online shoppers. By focusing on this 20%, Amazon was able to become the dominant player in the online retail space.
Koch also discusses the power of the 80/20 Principle in personal productivity. He suggests that people should focus on the 20% of tasks that will generate 80% of their results, rather than trying to do everything at once. He gives the example of Tim Ferriss, author of The 4-Hour Work Week, who suggests that people should focus on the most important tasks for just four hours a week, rather than trying to do everything all the time.
Overall, these examples and anecdotes from the book illustrate how the 80/20 Principle can be applied in many different areas of life, from business to personal productivity to wealth distribution. By focusing on the most important 20%, people and businesses can achieve greater results with less effort.

In The 80/20 Principle, Richard Koch explains how the Pareto Principle can be applied to all aspects of life and business to achieve greater efficiency and success. The book highlights the importance of focusing on the 20% of activities that yield 80% of the results, and how this principle can be used to prioritize tasks, streamline processes, and increase productivity.
Koch also emphasizes the need to challenge conventional wisdom and think creatively to find new ways to apply the 80/20 Principle. He provides numerous examples of individuals and companies who have successfully used this principle to achieve extraordinary results, and encourages readers to do the same.
Overall, The 80/20 Principle is a valuable resource for anyone looking to improve their personal or professional life by focusing on the most important activities and maximizing their impact.
