今天很残酷，明天更残酷，后天很美好，但绝对大部分是死在明天晚上，所以每个人不要放弃今天。
Today is cruel, tomorrow is crueler, and the day after tomorrow is beautiful, but most people die tomorrow night, so don't give up today.
La vertu ne peut aller sans la liberté.
获得智慧是一种道德责任，它不仅仅是为了让你们的生活变得更加美好。有一个相关的道理非常重要，那就是你们必须坚持终身学习。如果不终身学习，你们将不会取得很高的成就。光靠已有的知识，你们在生活中走不了多远。
Wisdom acquisition is a moral duty. It’s not something you do just to advance in life. And there’s a corollary to that proposition which is very important. It means that you’re hooked for lifetime learning, and without lifetime learning you people are not going to do very well. You are not going to get very far in life based on what you already know.
Some women choose to follow men, and some women choose to follow their dreams. If you're wondering which way to go, remember that your career will never wake up and tell you that it doesn't love you anymore.
The world loved man when he smiled. The world became afraid of him when he laughed.
