学而时习之，不亦说乎？
Is it not a pleasure, having learned something, to try it out at due intervals?
Source: 论语·学而(The Analects)
Background
This quote opens the Analects, reflecting Confucius deep understanding of learning. Learning is not just about acquiring knowledge, but more importantly about constantly reviewing and applying what we have learned in practice.
Interpretation
Confucius emphasizes three levels of learning: learning (acquiring knowledge), practicing (practical application), and joy (inner happiness). True learning should be a cyclical process of deepening understanding through continuous practice.
