Indeed, when one has met his basic needs and have more to spare, it is time to spend or give some to experience happiness. This is because happiness is really a state of in-and-out flow of one's energy. Using or giving money is an expression of out-flowing of one's life-state. Attempt to just hoard more and more in the belief that it brings more happiness can lead to the opposite result if only because the means – that is the pursuit of money for happiness – has unwittingly become the ends.
