I'm seeing big billionaires, they have extremely huge amount of money and also they are not investing their money for the betterment of the society and removing poverty or eliminating illiteracy or climate change instead having that much of money is not satisfactory for them and they are chasing for more.
One example is Elon Musk, he is at about 700 billion $ but still he is not satisfied.
What is inside us which never gets fulfilled?
Why we always see outside and wanted something, we don't know what but something with fulfils our all desires?
