How anyone can become more effective with less effort by learning how to recognize and apply the 80/20 principle, which states that 80% of all of our accomplishments in life and business come from only 20% of our efforts. One of the best-kept secrets of highly efficient individuals and groups is the 80/20 rule. For instance, did you know that 20% of consumers generate 80% of revenues? that we complete 80% of our task in 20% of the time we spend on it? The 80/20 Principle explains how, by concentrating our efforts on the 20% that truly matters, we can accomplish far more with a lot less work, time, and resources. Despite the fact that the 80/20 principle has long had an impact on business, author Richard Koch explains how it operates and demonstrates how we may apply it in a systematic and useful manner to greatly improve our performance, as well as our careers and businesses. The unstated implication of the 80/20 rule is that only a small portion of the things we spend our time on are truly important. We can, however, unleash the huge potential of the magic 20 percent and drastically improve our performance in our jobs, careers, enterprises, and personal lives by focusing on those things that already work.
