Quotes by Confucius
What you do not want done to yourself, do not do to others.
When you see a good person, think of becoming like her/him. When you see someone not so good, reflect on your own weak points.
Before you embark on a journey of revenge, dig two graves.
By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest.
To see what is right and not do it, is the want of courage.
