- Hitomi Kinue — Aloof? I Never Could Be
"When I lose, what kind of face will the people of Japan have when they look at me?" At nineteen, setting out alone for Sweden, that was what frightened her most. The story of the first Japanese woman to win an Olympic medal, who could never stay aloof.
- Kitasato Shibasaburo — The Man Who Wouldn't Listen
"Being a doctor or a monk is no work for a grown man with arms and legs." That, it is said, was how a young man felt when he entered a medical school only as a trick. Later he snapped at his bosses, cut down his own teacher's theory, and quit with all his staff when his institute was moved to a government office. What was the one piece of advice this man who never listened finally kept?
- Miyamoto Musashi — The Master Who Never Met His Time
"I did not win because I had mastered the art of fighting." The man who never lost wrote this at sixty. He never served any lord, was laughed at by a child for being a coward, and failed at a painting in front of his lord. The proud, bluffing life of a swordsman.
