"We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten. Don't let yourself be lulled into inaction."

Change is not merely necessary to life—it is life.

“唯一真正无限的是人类的灵魂。”

出自北齐·颜之推《颜氏家训·教子》。慈，慈爱。则，那么。畏慎，畏惧、谨慎。矣，句末语气助词。父母有威严也有慈爱，那么子女就会畏惧、谨慎而生孝顺之心。孝子是靠严格而慈祥的方法培养出来的，不是一味溺爱就能教育出来的。
