The beauty of mathematics lies in its ability to simplify the complex.

Look at a day when you are supremely satisfied at the end. It's not a day when you lounge around doing nothing; it's a day you've had everything to do and you've done it.

I don’t need anyone to complete me. I complete myself.

In the darkness, we find the light of our own humanity.

当你找不到人来喝你沏的茶时，当没有人需要你时，我想这就是人生完结的时候。
