The significantwords found on an old key —"If I rest, I will rust"—would be an excellent motto for those who are tired of their slightest bit of idleness
(懒散).
Those who would attain the heights reached and kept by great men must keep their abilities polished by constant use, so that they may unlock the doors of knowledge, the gates that guard the entrance to the professions, to science, art, literature, or agriculture —- every department of human efforts.
Industry(勤奋)　keeps bright the key that opens the treasury of achievement.
If Hugh Miller, after working hard all day in a mine, had devoted his evenings to rest and relaxation, he would never have become a famous geologist. The outstanding mathematician, Edmund Stone, would never have published a mathematical dictionary, never have found the key to the science of mathematics, if he had given his spare moments to idleness. Had the little Scottish boy, Ferguson, allowed his busy brain to go to sleep while he tended sheep on the hillside instead of calculating the positions of the stars by a string of beads, he would never have become a famous astronomer.
