3. Preventing before something happens is called prevention, stopping before it happens is called saving, and taking responsibility after doing it is called warning. Prevention is the top, saving is the second, and warning is the bottom. ——(Eastern Han Dynasty) Xun Yue

Translation: Preventing bad things before they happen is the best policy; preventing bad things when they first happen is the second best policy; and punishing bad things after they happen is the worst policy. This passage theoretically explains that control after the event is inferior to control during the event, and control during the event is inferior to control before the event.

4. Humility to superiors is a duty; humility to peers is kindness; humility to subordinates is nobility; humility to everyone is safety. ——(Ancient Greece) Aristotle

5. When gliding on thin ice, speed is safety.

——(USA) Emerson
