The land gives us everything; we must give something back.

——〈在广州岭南学堂的演说〉，1912年5月7日

数学是理性的音乐。

Innovation is the lifeblood of any company that wants to stay relevant in a rapidly changing world.

译文：奉承的话顺从了人的内心容易让人高兴，直率的话不能接受让人容易发怒。赏析：奉承的话虽然好听，但能让人迷失自我，直率的话虽然逆耳，但能让人清醒。我们少听阿谀的谗言，多听直率的忠言。

The most successful companies are those that listen to their customers and evolve with their needs.

心理学必须基于事实，而非假设。
