First, we must have ambition, second, we must be knowledgeable, and third, we must have perseverance.

From: Anonymous "The ancients talk about reading"

Original text:

When reading, Gai scholars should be ambitious, knowledgeable and persistent. If you are ambitious, you will never be willing to be dirty; If you have knowledge, you know that knowledge is infinite, and you dare not sell yourself short. Such as Hebo watching the sea, such as a well frog peeping into the sky, no one knows; Nothing is impossible with perseverance. These three are indispensable.

When reading, a scholar should have ambition, knowledge and perseverance. If you have ambition, you will never be willing to be inferior; If you are knowledgeable, you will know that there is no end to learning. If you have no experience, you will not be satisfied with yourself. For example, Hebo looks at the sea and the frog at the bottom of the well looks at the sky, all of which are ignorant; With perseverance, nothing is impossible. Aspiring, erudite and persistent are indispensable.

Zhu Du's "Three Coming and Three Going"

Original text:

I have tasted reading three times, that is, heart, eyes and mouth. The heart is not here, the eyes don't look closely, the heart is not single-minded, it can only read, never remember, and it won't last long. Of the three, the heart is the most urgent. Since the heart is here, won't the eyes be there?

Translation:

I once said: reading pays attention to "three", that is, when reading, you should concentrate, read carefully and read aloud. If the heart is not in the book, then the eyes will not look carefully; Because the mind and eyes are not centralized and unified, they just look casually and will not remember. Even if they do, they will not remember for a long time. Of the three, the heart is the most important. If you concentrate, will your eyes and mouth wander?
