“The will to do, the soul to dare.”

“Courage is fire, and bullying is smoke.”

“I have nothing to offer but blood, toil, tears and sweat.”

“Courage, not compromise, brings the smile of God's approval.”

“Facing it — always facing it — that's the way to get through.”

“Time goes by, reputation increases, ability declines.”

“In our era, the road to holiness necessarily passes through the world of action.”

“We are not permitted to choose the frame of our destiny. But what we put into it is ours.”

“Your cravings as a human animal do not become a prayer just because it is God whom you ask to attend to them.”

“In the last analysis it is our conception of death which decides our answers to all the questions life puts to us.”

“What makes loneliness an anguish is not that I have no one to share my burden, but this: I have only my own burden to bear.”
