The general belief is that money cannot buy happiness. This is based on the premise that being rich does not equate to greater happiness.
However, Evidence is beginning to show that money can really buy happiness. Just as you might have a lot of money to buy the best car in the world, you cannot own this car unless you actually go to the car shop and actually purchase the car. The same things relates to happiness.

To use money to buy happiness, you will need to go to the happiness shop. Unfortunately the happiness shop is not the same as the car shop, as it is not so obvious. Research has shown that the way to get to this shop is to spend your money on other people, rather than on your self. This must be done with a genuine interest in helping somebody else. Tremendous happiness comes from this gesture far and above any happiness you might get from buy a new private jet or any item of great value for your own personal enjoyment.
