在数学研究中，坚持是关键；许多伟大的成果来自于一遍又一遍地从不同角度看待同一个问题。
Persistence is key in mathematical research; many great results come from looking at the same problem from different angles over and over again.
You are someone I will never forget.
I think you have to be who you are. I don't think you can fabricate it. I think you have to be who you are and hope that people will accept you for who you are.
真正的发现之旅不在于寻找新的风景，而在于拥有新的眼光。
我宣告：自由是人生的终极目标。
The most sustainable product is one that lasts.
