Question

Those who would attain the heights reached and kept by great men must- keep their ability polished by constant use, so that they may unlock the doors of knowledge, the gate that guard the entrances to the professions, to science, art, literature, agriculture—every department of human endeavor.
Industry keeps the key bright that opens the treasury of achievement.If Hugh Miller, after toiling all day in a quarry, had devoted his evenings to rest and recreation, he would never have become a famous geologist.The celebrated mathematician, Edmund Stone, would never have published a mathematical dictionary, never have found the key to science of mathematics, if he had given his spare moments to idleness, had the little Scotch lad, Ferguson, allowed the busy brain to go to sleep while he tended sheep on the hillside instead of calculating the position of the stars by a string of beads, he would never have become a famous astronomer.
Labor defeats all—not inconstant, or ill-directed labor; but faithful, persistent, daily effort toward a well-directed purpose.So industry is the price of noble and enduring success.
