Money doesn't buy happiness directly, however, it sure helps.

You can travel, buy stuff and do whatever you want without much worries or family problems.
Most of the arguments at every household is directly related to money, either one of the members of the household used too much or used on something the other doesn't feel is essencial.

Does money always bring happiness? No!! Of course not. It might never bring either but that depends on each and everyone of us.
