Money is overrated. Truly new things rarely need an abundance of money. If that was so， billionaires would have a monopoly on inventing new things， and they don’t. Instead almost all breakthroughs are made by those who lack money， because they are forced to rely on their passion， persistence and ingenuity to figure out new ways. Being poor is an advantage in innovation.

An excellent man; he has no enemies; and none of his friends like him.

作战虽然讲究排兵布阵，但士兵的勇敢是其中的根本;丧葬虽然讲究礼节，但对亲人的哀思是其中的根本;一个人虽然很有学识，但思想道德、行为举止是其中的根本。
