Is what you have useful?
In this case, for example, the assets owned by humans are science or knowledge. When someone has the knowledge, there are those who can take advantage of their knowledge and some who cannot use their knowledge. To use knowledge to be useful is to practice and teach the knowledge they have, if someone has knowledge of how to grow tomato trees, this knowledge will be useful when this person practices by planting tomato trees and teaches others how to grow tomato trees. When this person grows tomato trees to take his own hands, the knowledge he has is beneficial for himself, but when this person teaches the science of growing tomatoes to others, the knowledge he has is beneficial for others and automatically for himself too.
The next asset that can be taken advantage of is property which has a broader meaning, not just money, gold, and other similar valuables. When a person has a tomato seed, this can also be included in the term possessing property. This type of asset will not be useful when it is only stored, so it is not profitable for the owner. For example, having a lot of money and only depositing it in the bank, when the person who owns this money dies, the money he owns will no longer be of use to him. The money may be taken by other people and used by others.
Especially when someone believes that there will be life after death, saving and not using money while still alive is an unprofitable choice. There is a term about investment in the hereafter which is by utilizing assets while still living in the world with the belief that these assets used will provide benefits in the hereafter. Although not everyone believes in the afterlife, very few people do not believe in the death and it can be a lesson that when humans die, they cannot use the assets they have anymore.
