Money makes the world go round. Actually, I think it's something to do with the gravitational pull of the sun. But we can blame money if we like.
It's good to have money and the things that money can buy, but it's good, too, to check up once in a while and make sure that you haven't lost the things that money can't buy.
A wise man should have money in his head, but not in his heart.
A billion here, a billion there, pretty soon it adds up to real money.
