1. Napoleon said: A soldier who does not want to be a general is not a good soldier.

2. The filament Edison first discovered was made of bamboo charcoal, and was later improved into tungsten filament. Edison made more than a thousand inventions and creations throughout his life, some of which have been astonishingly successful. He is also famous himself.

However, he never indulged in his inventions. He was always climbing into new fields of science. At the same time, he was always negative about his inventions and made improvements without stopping.

He himself said: "I will never be satisfied." Endless study and non-stop improvement are another outstanding feature of Edison.

Extended information:

"He who is dissatisfied is always happy" This is an attitude that indicates always being enterprising. It is a positive attitude that is not satisfied with the status quo and strives to change. It guides people to keep improving. Work hard and forge ahead in the direction of the people, thereby promoting the development of society. Stick to the right values.

Only when you are not satisfied can you have the motivation to move forward; only when you are not satisfied can you have a better life; only when you are not satisfied can you always be happy.

Not being satisfied is the fundamental point of the country.

Qin Shihuang was able to unify China because he was dissatisfied countless times, so he continued to reform and improve, which made Qin strong.

Mencius once said: "If you enter, you will be helpless, and if you leave, you will be invincible, the country will perish."

If a country is content with the status quo and has no "ambition", will perish.

China's reform and opening up, the American War of Independence, and the French Revolution have all proven to us the importance of dissatisfaction to the country.

Only when one is not satisfied can one have a sense of urgency, and only when one is not satisfied can one revitalize the country and create a new world.
