Modern Meaning
In "知之为知之,不知为不知,是知也," Confucius focuses on to know what you know, and to know what you do not know. The exact principle is that wisdom has to become a visible pattern of conduct, not a sentence one merely agrees with. The tension is not generic conduct; it is the specific problem that people understand a principle abstractly but fail to choose the behavior it requires in the next situation, which still appears in facing a routine decision where character is easier to postpone than practice.

Because this line says "To know what you know, and to know what you do not know," translate the sentence into one observable behavior and do it before the day ends, so the lesson becomes visible in one behavior.
