Money is just a commodity for some and for some it is oxygen. People all over the world crave for what only a very minute percentage of the entire world population owns.
Who says money cannot buy happiness. It can, if you know where to shop for it. Should we then start for desiring money, I guess not. We should desire the purchasing power that money has, that's what we should look for. At times the purchasing power is also bestowed in other neglected things. So look for the power that comes with money.
