“Don’t get hung up on the little things. Focus on the 20% that determines everything.”

The 80/20 Rule has been translated into 40 languages ​​and sold over a million copies worldwide, and continues to exert enormous influence.
The '80/20 rule' is an immutable law that applies to almost all phenomena, including life and business.
If you can properly understand this law that 20% of your input produces 80% of your results, you will be able to manage your time, self, and network in a way that is close to a revolution.
Individuals can live happier and more effective lives, and for-profit businesses can earn significantly more profits.
This law enables all individuals and organizations to achieve more valuable results with less effort, cost, and investment.
As Tim Ferriss, one of the "Best Young Innovators of Our Time" by Fast Company, Forbes, and Fortune, puts it, "If you read this book and apply it," your life will be completely different.

We often think that if we invest 50%, we will get 50% back, and that this is natural and fair.
But the 50/50 mindset is a dangerous idea that is deeply ingrained in our consciousness.
The 80/20 rule means that there is an imbalance between two causal relationships.
This ratio can be 65 to 35, 70 to 30, 75 to 25, 80 to 20, 95 to 5, 99.9 to 0.1, or any other number in between, and the two numbers do not necessarily have to add up to 100.
When we apply the 80/20 rule, we are surprised to see that the degree of imbalance exceeds our expectations.
Company executives may anticipate that certain buyers and certain products will be more profitable than others.
But if you check the ratio, you might be so surprised that you will be speechless.
Teachers vaguely know that a small number of students cause most of the school rules violations and problems, but when they investigate directly, they find that the imbalance is much greater than they expected.

It has been frequently observed since ancient times (probably since the 1950s) that 80% of the quantity measured comes from 20% of the people or things.
Although the numbers are rarely exactly 80/20, 80/20 has become a symbol of this imbalanced relationship.
Also, when we conventionally talk about 80/20, the 20% represents the top, not the bottom, and in fact, it focuses on the important consumers or causes at the top.
For beer companies looking to promote their brands or understand what customers think about the beers they produce, studying the top 20% is obviously the most useful.

People with an 80/20 mindset believe that life should be enjoyable and find fulfillment in excitement, joy, and a desire for future happiness.
Almost everyone wants to live a happy life, but many people either don't know the simple path to happiness or, even if they do, don't put it into practice.
Usually, we fall into one or more of the following traps:
You spend a lot of time with people you don't really like.
Doing things you don't want to do in the name of 'making a living'.
You spend most of your 'free time' doing things that aren't even that enjoyable.
If we turn this around, the meaning becomes clearer.
Most people spend too little time with the people they love and too little time doing things they enjoy.
--- p.76, from “Chapter 3 Declaration of Freedom”

We must be decisive when eliminating low-value activities.
Under no circumstances should everyone be given equal amounts of time.
Above all, you must immediately get rid of the habit of doing things because 'someone else asked you to' or 'I took the call.'
As Nancy Reagan advised, if you don't like something, just say 'No.'
Alternatively, 'completely ignoring' is another option.

The disparity is even more pronounced when comparing the income of superstars to that of the general population, with ratios typically exceeding 80-20, often reaching 90-10 or even 95-5.
Many have tried to explain the enormous income that goes to superstars in economic or social terms.
The most compelling argument is that two factors have contributed to the increase in superstars' earnings.
One is that with the help of the mass media, many people can enjoy the activities of superstars simultaneously.
Janet Jackson, J.
Rowling, Steven Spielberg, Oprah Winfrey, Mariah Carey, and David Beckham have increasingly large audiences, meaning the additional cost of "distributing" themselves to these growing audiences is virtually zero.
Even if there are additional costs for broadcasting, producing CDs, and publishing books, these only account for a small portion of the overall expenses.
Even if you give a superstar millions or tens of millions of dollars, the increased cost per customer is only a few cents or even less than a cent.
It costs much less than the average person would to earn much less than they do.

The reason the 80/20 rule is becoming increasingly effective is because of the power of networks.
The network operates according to the 80/20 rule.
In any market or category, very few networks dominate the majority of activity and business in that market or category.
Networks and their members love market concentration and monopoly.
Because it provides the greatest breadth and depth to the network.
The larger the network, the better, as it matches supply and demand more quickly and efficiently.
This is because there are more permutations of possible member matches and more bias data for each member.
