出自《论语·公冶长》。做事情，一定要通过反复的思考，再去行动。

The creative act is not pure. History evidences it. Ideology demands it. Society exacts it. The artist loses his freedom the moment he creates a work of art.

The possibility of finding a planet similar to Earth is what drives our passion for exoplanet research.

最痛苦的事情是在太爱一个人的过程中失去自己，忘记了你也很特别。
