Quote by Denis Diderot

"The world is for those who think."

"Man will never be free until the last king is strangled with the entrails of the last priest."

"Nothing can be believed unless it is seen."

"The first step toward philosophy is incredulity."

"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."
