Extra posting : Why people cooperate with one another? How do they know what to do? ( Posting by Jihye Um)

Q . Why people cooperate with one another? How do they know what to do?

: There is a finite range of individuals available.
People who are good at science or people who are good at painting, everyone has a good part.

However, there are limits to individuals working alone.

But if you work together and cooperate, you save time rather than doing it alone.
And you can produce better results than you can do alone. 

Also, if you work together, you can easily supplement the less fortunate when you work alone.

There is also a strong advantage that the cooperation of these people will enhance the competitiveness of the national level.

That is why countries interact with other countries.
These are the reasons why people work together to cooperate with others.
