Chapter 20(I) - Doctrine of the Mean

"The superior man, while there is anything he has not studied, or while in what he has studied there is anything he cannot understand, Will not intermit his labor. While there is anything he has not inquired about, or anything in what he has inquired about which he does not know, he will not intermit his labor. While there is anything which he has not reflected on, or anything in what he has reflected on which he does not apprehend, he will not intermit his labor. While there is anything which he has not discriminated or his discrimination is not clear, he will not intermit his labor. If there be anything which he has not practiced, or his practice fails in earnestness, he will not intermit his labor. If another man succeed by one effort, he will use a hundred efforts. If another man succeed by ten efforts, he will use a thousand.

"Let a man proceed in this way, and, though dull, he will surely become intelligent; though weak, he will surely become strong."
