《新唐书·列传·卷八十二》
毛病在策略经常变更，军队无所适从；担任要职的人不能确保有才能，有才能的人不能确保担任要职；显达的人不一定有真实本领，有真实本领的人不一定能显达；受信任的人不一定忠诚，忠诚的人不一定受到信任；实行的措施不一定正确，正确的措施不一定会施行。
病在谋无定用，众无适从；任者不必才，才者不必任；闻不必实，实不必闻；所信不必诚，所诚不必信；行不必当，当不必行。
The problem lies in the frequent changes of tactics, which make the army at a loss; those who hold important positions cannot be assured of their talent, and those who have talent cannot be assured of holding important positions; the influential people do not necessarily have real ability, and those who have real ability do not necessarily become influential; those who are trusted are not necessarily loyal, and those who are loyal are not necessarily trusted; the measures that are implemented are not necessarily correct, and the correct measures will not necessarily be implemented.
