Success = hard work + correct methods + less empty words. ——Einstein

The work is accomplished by hard work but neglected by play; the success is achieved by thinking but destroyed by casualness. ——Han Yu

There are three aspects of reading, namely, understanding with the heart, understanding with the eyes, and understanding with the mouth. If your mind is not here, your eyes will not be able to read carefully. If your mind is not focused, it will just recite and read. You will never remember it, and it will not last long.

Among the three arrivals, the heart is the most urgent. Once the heart has arrived, won’t the eyes and mouth not care? ——Zhu Xi's "Regulations on Training and Learning"
