数学家的工作永远不会真正完成；总有更多的东西需要探索。
A mathematician's work is never truly finished; there is always more to explore.
Be thankful for what you have; you’ll end up having more. If you concentrate on what you don’t have, you will never, ever have enough.
品质是我们的生命线，绝对不能妥协。
世界是残酷的，我的书反映了这一点。
孤独是自我的贫乏；独处是自我的丰富。
我不怕黑暗，我怕黑暗中的东西。
Time erodes all such beauty, but what it cannot diminish… is the wonderful workings of your mind. Your humor, your kindness… and your moral courage.
