MILLIONAIRE: “Son, to make it in business you’ve got to live by two principles, honesty and wisdom.”

SON: “What do you mean by that, Dad?”

MILLIONAIRE: “Be honest in business.  If you promise to do something, keep your word even if you have to go bankrupt to do it.”

SON: “And what about wisdom?”

MILLIONAIRE: “That’s simple to explain, son.  Never make any promises.”
