"The American system of ours gives each and every one of us a great opportunity."

"There is one thing that the American people always rise up and do--when they get ready."

"I am nothing in this world but a writing machine."

"Success comes to those who never give up."

"Success is measured by happiness, not money."

"You make your own luck in this world."

"You have to be organized to be successful in anything."
