老年人无所谓不信；中年人无所不疑；年轻人无所不知。
The old believe everything; the middle-aged suspect everything; the young know everything.
The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.
The best way to predict the future is to create it through innovation and adaptation.
The future belongs to those who can balance profitability with responsibility.
译文：结交朋友如果是为了脸面有光，那不如结交对自己有身心有益的朋友；教导子弟求取富贵荣华，不如告诉子弟们养成良好的品行。赏析：《大学》一书中说：自天子以至于庶人，壹是皆以修身为本。意思是说，不管是天子还是百姓，都应该把修身作为自己的立身之本。做事就是做人，人做好了，事情自然就会成。
这个世界大多时候是对的。这个世界大多时候是错的。
