My understanding of business

Business is about the exchange of ‘Products/Goods and Services’.
Products are made (with time/energy/effort/some overheads or investments) and sold for a profit. The same holds true for services too.

The insight I had was that money is actually only a signifier.
Money has no value in and of itself.
Its value is only its potential to acquire products and services of value.

Supposing someone buys something for 100 and sells it for 200,
He makes a profit of 100.
But what can he do with this 100, it is only once again used to buy other products and services made or offered by other people.
So the money is simply fed back into the same system.
This system I would guess is what is referred to as the ‘world economic engine’.

Imo it bears a close resemblance to the circulatory system of blood we have in our bodies.
Money is the blood, and is used as the MEDIUM for exchange of resources (products and services).
The system is self contained, and the resources it transports are:
# Services: Direct human effort
# Products which are transformations of the resources of the earth (also created by human effort).
# Certain other living creatures on the earth that are owned in some way by individuals or governments, and some of the earth’s natural resources (esp. the rare ones).

Also, ultimately speaking,
‘All business is about the enhancement or maintenance of human well-being’ (inspired from Sadhguru).
