The 10,000-hour rule is a law pointed out by writer Gladwell in his book "Outliers". "The reason why geniuses in people's eyes are extraordinary is not because of their superior talent, but because of their continuous efforts. 10,000 hours of training is a necessary condition for anyone to transform from an ordinary person to a world-class master." He called this "The 10,000-hour rule."

Why 10,000 hours?

The key to the "10,000 hours rule" is that 10,000 hours is the minimum, and there are no exceptions. No one achieves world-class performance with just 3,000 hours; not even 7,500 hours; it has to take 10,000 hours—ten years, three hours a day—no matter who you are. This is equivalent to telling everyone that 10,000 hours of practice is the only way to success.

Mingyue, who wrote "Those Things in the Ming Dynasty", started reading history when he was 5 years old. He read "Up and Down Five Thousand Years" seven times before he was 11 years old, and started reading "Twenty Years Old" after he was 11 years old. "Four Histories", "Zi Zhi Tong Jian", and then "Ming Shi Lu", "Qing Shi Lu", "Ming History Chronicles", "Ming Tong Jian", "Ming Huidian" and "Compendium Three Parts". He has been reading it for 15 years, and has probably read more than 60 million words of historical materials in total, and he has to study for two hours every day. Multiply these time numbers, 15 years times 2 hours and then times 360 days, equals 10,800 hours. That's why he, who works in the customs, can be a civil servant during the day and become an online writer at night, coding in front of the computer.

In fact, there is another way to express ten thousand hours, which is "ten years". As early as the 1990s, Nobel Prize winner in economics and scientist Herbert Simon and Erikson established the "ten-year rule". They point out that it generally takes about 10 years of hard work to become a master in any field. It is not difficult to think of the ancient Chinese saying "it takes ten years to sharpen a sword", but it is actually the same truth.

Countless facts have proved that as long as a person is not too stupid or too inexperienced, with ten thousand hours of hard training, even if you cannot become a master or a great master, you will at least become a leader in this industry. An expert with rich experience, a person useful to society.
