“We can't control our destiny, but we can control who we become.”

“There is nothing constant in the universe. All ebb and flow, and every shape that's born, bears in its womb the seeds of change.”

“Anything that is conceivable is possible.”

“Mankind owns its destiny, and its destiny is the earth. We are destroying it until we have no destiny.”

“If we could but recognize our common humanity, that we do belong together, that our destinies are bound up in one another's, that we can be free only together, that we can be human only together, then a glorious world would come into being where all of us lived harmoniously together as members of one family, the human family.”

“Our lives are fashioned by our choices. First we make our choices. Then our choices make us.”

“What is done cannot be undone, but one can prevent it happening again”
