A fool's bolt may sometimes hit the mark.

愚者千虑，必有一得。

A still tongue makes a wise head.

智者寡言。

Call no man happy until he dies.

盖棺才能定论。

Custom makes all things easy.

若照习惯办，万事皆不难。

Feed by measure and defy physician.

饮食有节制，医生无用处。

He who has lost his good name is a dead man among the living.

丧失好名誉，犹如活死人。
