The shortest way to do anything is to do only one thing at a time. —Cecil.
The power of concentration is one of the most valuable of intellectual attainments. —Horace Mann.
The power of a man increases steadily by continuance in one direction. —Emerson.
Careful attention to one thing often proves superior to genius and art. —Cicero.
"It puffed like a locomotive," said a boy of the donkey engine; "it whistled like the steam-cars, but it didn't go anywhere."
The world is full of donkey-engines, of people who can whistle and puff and pull, but they don't go anywhere, they have no definite aim, no controlling purpose.
The great secret of Napoleon's power lay in his marvelous ability to concentrate his forces upon a single point. After finding the weak place in the enemy's ranks he would mass his men and hurl them upon the enemy like an avalanche until he made a breach. What a lesson of the power of concentration there is in that man's life! He was such a master of himself that he could concentrate his powers upon the smallest detail as well as upon an empire.
When Napoleon had anything to say he always went straight to his mark. He had a purpose in everything he did; there was no dilly-dallying nor shilly-shallying; he knew what he wanted to say, and said it. It was the same with all his plans; what he wanted to do, he did. He always hit the bull's eye. His great success in war was due largely to his definiteness of aim. He knew what he wanted to do, and did it. He was like a great burning glass, concentrating the rays of the sun upon a single spot; he burned a hole wherever he went.
The sun's rays scattered do no execution, but concentrated in a burning glass, they melt solid granite; yes, a diamond, even. There are plenty of men who have ability enough, the rays of their faculties taken separately are all right; but they are powerless to collect them, to concentrate them upon a single object. They lack the burning glass of a purpose, to focalize upon one spot the separate rays of their ability. Versatile men, universal geniuses, are usually weak, because they have no power to concentrate the rays of their ability, to focalize them upon one point, until they burn a hole in whatever they undertake.
This power to bring all of one's scattered forces into one focal point makes all the difference between success and failure. The sun might blaze out upon the earth forever without burning a hole in it or setting anything on fire; whereas a very few of these rays concentrated in a burning glass would, as stated, transform a diamond into vapor.
