It turns out money CAN buy you happiness, as long as that happiness is an experience you will anticipate in the future! During the time leading up to that experience, you will experience the highest level of life satisfaction. Moreso than in anticipation of a material purchase, and moreso than an experience that occurs right away, and you don't have the time to anticipate.
And although this article doesn't say it, I can say from experience and other reading, buy that future experience on credit is not a way to increase the happiness quotient!
