"You can't buy happiness."

I can never figure out who originally said it, but i love the quote (which i may be mangling of course) "I've been rich and unhappy, and I've been poor and unhappy, and I can tell you that rich is better."

And yeah, i've seen reports about that study too. Once you're over $40k being happy is more important than being rich, but there's a pretty strong causation between poor and unhappy =P
