All of us know that nothing is ours permanently, then why do we suffer so much to have more and more?

Explanation

It is true that nothing belongs to us permanently because one day we have to leave all the things on the earth. Nevertheless, people crave more wealth, fame, knowledge, beauty, and even crime because this is human nature. We cannot separate ourselves from such things. If we give up our greed to have more and more, the world would be a much better place to live in. People would not go to extremes to achieve something.
