Greetings Friends,
It's true that money can't buy everything. But, it is also a bitter truth that poverty can't buy anything. There is nothing bad for a person than to live as a poor. Life becomes miserable. No one respects a poor man. So, when people say that rich people do not have peace of mind or rich are deprived of real happiness, you should understand that those people are just trying to conceal their poverty through these words. Money can't buy everything, but it can buy many things, including happiness.
So, keep investing on assets which may bring you more money. Money cannot bring everything for you but remember that poverty is a curse.
Stay happy!
