不矜细行，终累大德。
释义Explanation
这句话告诫人们，不要轻视琐碎细微的行为，因为每一次对细节的疏忽，都可能在日积月累中损害一个人的大德。它强调修身须从细微处入手，小节不守，大德难成。任何伟大的品格都建立在无数个看似微不足道的自律之上，忽视细节也就是在动摇根本。
This saying warns that ignoring minor actions gradually undermines one's great virtue. It emphasizes that self-cultivation must begin with attentiveness to small matters; without guarding minor details, lofty character cannot be sustained. Every noble quality is built on countless seemingly trivial acts of self-discipline, and neglecting them shakes the foundation of moral integrity.
使用场景Usage
在现代职场中，一个能力出众的人可能因经常迟到、言语轻率等“小节”而失去信任。家长教育孩子时，也可引用此句说明随手整理物品、守信守时等习惯，看似微小，却是塑造品格的基石。细节的累积效应最终决定一个人的德行高度。
In today’s workplace, a talented professional may lose trust due to repeated small shortcomings like tardiness or careless words. When teaching children, one might cite this to explain that habits like tidiness or punctuality, though minor, are the building blocks of character. The cumulative effect of small acts ultimately defines one’s moral stature.
