Money is a funny thing. It's just one of the great fictions the world as a whole has subscribed to, much like religion.
I for one don't care for money (and I am not rich. ATM, I would even suggets that I'm rather poor, at least relatively).
Still, money is what keeps the world turn round, so I have to play by the rules. But I am no less happy when I have little money than when I have more of it. At least as long as I can afford the luxury of having a roof over my head and a meal every day.
