Joy by Confucius

To be constantly learning and practicing what you learn, isn't it the greatest joy of all ?

To have bosom friends who share your learning from all over the world, doesn't it bring the greatest happiness ?

To be unknown to people and yet remain undisturbed, isn't that an act of the most virtuous man ?

--- The Analects , Chapter 1:1
