“I believe each human being has the potential to change, to transform one’s own attitude, no matter how difficult the situation.”

“For what then matters is to bear witness to the uniquely human potential at its best, which is to transform a personal tragedy into a triumph, to turn one’s predicament into a human achievement.”

“To know one’s own state is not a simple matter. One cannot look directly at one’s own face with one’s own eyes, for example. One has no choice but to look at one’s reflection in the mirror. Through experience, we come to believe that the image is correct, but that is all.”

“The heart of another is a dark forest, always, no matter how close it has been to one’s own.”

“Attitude is the first quality that marks the successful man. If he has a positive attitude and is a positive thinker, who likes challenges and difficult situations, then he has half his success achieved.”

“Everything can be taken from a man but one thing: the last of the human freedoms—to choose one’s attitude in any given set of circumstances, to choose one’s own way.”
