Science says that you'll be happier if you spend your money on experiences over material goods*.
Case in point: every cell phone I have ever bought made me unendingly happy when I first bought it. I always referred to my new phones as "sexy". How long did it take for them to be annoying and lame? (HINT: not very long). Now, this might have something to do with the fact that I mostly get the cheapest phones that have decent reviews online, but still.
Speaking of, does anyone remember what it used to be like to buy things before every product was extensively reviewed online? Because I don't, even though it seems I used to do it all the time.
*I am assuming that they are assuming you've already spent some money on, you know, food.
