It requires a great deal of boldness and a great deal of caution to make a great fortune, and when you have it, it requires ten times as much skill to keep it.
When the last tree is cut, the last fish is caught, and the last river is polluted; when to breathe the air is sickening, you will realize, too late, that wealth is not in bank accounts and that you can't eat money.

He can buy a library or visit the whole world, but perhaps has neither patience to read nor intelligence to see.... The purse may be full and the heart empty. He may have gained the world and lost himself; and with all his wealth around him ... he may live as blank a life as any tattered ditcher.
