If you can count your money, you don’t have a billion dollars.
As quoted by Robert Lenzner in his book, The Great Getty (1985)
My father said, 'You must never try to make all the money that's in a deal. Let the other fellow make some money too, because if you have a reputation for always making all the money, you won't have many deals'.
