He who has one strong faculty, the using of which would give delight and success, yet passes it by, to use a weaker faculty, is doomed to mediocrity and heart-breaking failure. The eagle has powerful muscles under the wings, but slender and feeble legs; the fawn lacks the weight of the draught horse, but has limbs for swiftness. Now, if an eagle should become a competitor in a walking race and if the fawn should enter the list of draught horses, we should have that which answers precisely to the way in which some men seek to gain their livelihood, by tying up their strongest gift and using their feeblest faculties. When it is said that only five merchants out of a hundred succeed we perceive that the great majority of men do not think to any purpose in choosing an occupation. Recalling his friends who had misfitted themselves, Sidney Smith once said: "If we represent the occupations of life by holes in a table, some round, some square, some oblong, and persons by bits of wood of like shapes, we shall generally find that the triangular person has got into the square hole, the oblong into the triangular, while the square person has squeezed himself into the round hole." For lack of wise thinking beforehand, multitudes have died of broken hearts midst failure and misery who might have achieved great happiness and success had they used their thoughts in choosing their life-work. He who approaches his task with a leaden heart is out of the race before he is in it. Success means that the heart loves what the hand does. The bread-winning problem is the one that touches us first and most closely, and to wise thoughts only is it given to solve that problem. The number and value of our thoughts determine a man's value to society. No investments bring so high a rate of interest as investments of brain. Hand work earns little, but head work much. In a Western camp one miner put his lower brain into the pickaxe and earned $2.00 a day; another miner put his higher brain into the stamp-mill and soon was receiving a score of dollars daily for his work; a third youth, toiling in the same mine, put his genius into an electric process for extracting ore, and sold his invention for a fortune. It seems that wealth was not in the pick, but in the thoughts that handled it. Had God intended man to do his work through the body, man's legs would have been long enough to cover leagues at a stride, his biceps would have been strong enough to turn the crank for steamships, his back would have been Atlantean for carrying freight cars across the plains.
