“We can enjoy just as much as we can use, and no more.”

“…All the good things of this world, are no farther good to us, than they are for our use; and that whatever we may heap up indeed to give others, we can enjoy just as much as we can use, and no more. The most covetous griping miser in the world would have been cured of the vice of covetousness, if he had been in my case, for I possessed infinitely more than I knew what to do with.”
— Robinson Crusoe by Daniel Defoe
