我不断看到有些人在生活中越过越好，他们不是最聪明的，甚至不是最勤奋的，但他们是学习机器。他们每天夜里睡觉时都比那天早晨聪明一点点。
I constantly see people rise in life who are not the smartest, sometimes not even the most diligent, but they are learning machines. They go to bed every night a little wiser than they were when they got up.
The night is a great library, but the stars are its books.
It is greed and thirst for power that brings wars and trouble to the world.
An idea is only as good as its execution.
对于那些感受的人来说，世界是一场悲剧，但对于那些思考的人来说，世界是一场喜剧。
音乐是通用的语言。
