“It is not the man who has too little who is poor, but the one who hankers after more. What difference does it make how much there is laid away in a man's safe or in his barns, how many head of stock he grazes or how much capital he puts out at interest, if he is always after what is another's and only counts what he has yet to get, never what he has already. You ask what is the proper limit to a person's wealth? First, having what is essential, and second, what is enough.”
