happiness and stuff

I've seen today a status on FB: I quote "happiness is overrated"
Mmmh... even I think it wasn't meant to be the quote of the day, but just a way to get again in touch with friends, it made me think... about happiness, sadness, life itself, feelings, perceptions, and so many other things we overrate or underrate.
In the end, it's the context that matters. And the persons who says it. And the listner. Or the reader.
the same thing has so versions... a version for every person on the earth. and we are so many...
Anyway, I think that happiness is, in fact, underrated. We should treasure more every happy moment.
