28 Law is also called 80/20 Law, Pareto Law is also called Balet Law, Juren Law, Key Minority Law, Minor Majority Law, Least Effort Law, Unbalance Principle, etc. Widely used in sociology and enterprise management.

The 28 Law was discovered by the Italian economist Pareto at the end of 19 and the beginning of the 20th century. He believes that in any group of things, the most important thing only accounts for a small part, about 20%, and the remaining 80% is secondary, although it is the majority, so it is also called the 28 th Law.

Practical significance:

The 80/20 rule is not only widely used in economics, management and other fields, but also has important practical significance for our own development: learn to avoid spending time and energy on trivial matters and learn to grasp the main contradictions.

A person's time and energy are very limited, and it is almost impossible to really "do everything well". We should learn to allocate time and energy reasonably. If you want to cover everything, you might as well make a breakthrough. Spend 80% of resources on 20% of key benefits, which can drive the remaining 80% of development.

The problems that can be solved by the "28 Law" include time management, key customers, wealth distribution, resource distribution, core products, key talents, core profits, personal happiness and so on.
