The most dangerous thought you can have as a creative person is to think that you know what you're doing.

We don't have to sacrifice taste for sustainability—we can have both.

We must constantly look at things in a different way.

读书人要为自己的一生爱惜名誉，不应为这一生出卖名誉。治理诗书，崇尚气节，谨慎取予，严肃仪表，这就是爱惜名誉。相互竞争标榜，攀附权贵，出尽风头，不分是非，这就是出卖名誉。爱惜名誉的人清静无为，出卖名誉的人急躁而拙劣。所以读书人要管理钱财正当用途，而不是浪费金钱。救济乡亲，聘请老师教学，赈济荒年歉收，协助善行，这些是运用钱财。而花钱布置庭园，唱歌跳舞，大宴宾客，积聚宝物等，这些都是浪费金钱。善用金钱的人虽花钱但收获丰盈，伤财的人积聚多但终将倾覆。
