money

They say money buys everything, but that is not true. You can buy food, but not appetite; medicine, but not health; soft beds, but not sleep; knowledge, but not intelligence; glitter, but not comfort; fun, but not pleasure; acquaintances, but not friendship; servants, but not faithfulness; grey hair, but not honour; quiet days, but not peace. The shell of all things you can get for money. But not the kernel. That cannot be had for money.
Arne Garborg

If nothing will serve a man but rich clothes and furniture, statues and plate, a numerous train of servants, and the rarities of all nations, it is not Fortunes's fault, but his own, that he is not satisfied; for his desires are insatiable, and this is not a thirst, but a disease; and if he were master of the whole world, he would be still a beggar. It is the mind that makes us rich and happy, in what condition soever we are; and money signifies no more to it than it does to the gods.
Seneca
