The beauty of mathematics is that it is so simple yet so powerful.

The way we communicate with others and with ourselves ultimately determines the quality of our lives.

译文：与别人不去争长短，常常懂得知足，心情就会平静没有忧愁担心。赏析：不与人争得失，惟求己有知能。事事争个输赢，比个高低，烦恼就会很多，灾难也就更多。如果放低姿态，懂得知足常乐，事情自然就会水到渠成。

We work with what is there because it has value.

黑色不是单一的，它是多样的。

记住，希望是好事，甚至也许是人间至善。而美好的事永不消失。
