Si quieres comprar felicidad harás mejor invirtiendo en una experiencia en vez de en una cosa.

If you want to buy happiness you are much better off buying an experience rather than a thing.  That's because a thing like a car, new clothes, or cool gadget will always wear down, break down over time, while an experience, like going to the Galapagos, or a great concert, will only improve over time. You'll always have it (Paris, bunjee jumping, that meal) forever. In the long term an experience delivers more happiness per dollar.
