"Know thy work and do it," said Carlyle; "and work at it like a Hercules."
"Whoever is resolved to excel in painting, or, indeed, in any other art," said Reynolds, "must bring all his mind to bear upon that one object from the moment that he rises till he goes to bed."
"I have no secret but hard work," said Turner, the painter.
"The man who is perpetually hesitating which of two things he will do first," said William Wirt, "will do neither. The man who resolves, but suffers his resolution to be changed by the first counter-suggestion of a friend—who fluctuates from opinion to opinion, from plan to plan, and veers like a weather-cock to every point of the compass, with every breath of caprice that blows,—can never accomplish anything great or useful. Instead of being progressive in anything, he will be at best stationary, and, more probably, retrograde in all."
Perseverance built the pyramids on Egypt's plains, erected the gorgeous temple at Jerusalem, inclosed in adamant the Chinese Empire, scaled the stormy, cloud-capped Alps, opened a highway through the watery wilderness of the Atlantic, leveled the forests of the new world, and reared in its stead a community of states and nations. Perseverance has wrought from the marble block the exquisite creations of genius, painted on canvas the gorgeous mimicry of nature, and engraved on a metallic surface the viewless substance of the shadow. Perseverance has put in motion millions of spindles, winged as many flying shuttles, harnessed thousands of iron steeds to as many freighted cars, and set them flying from town to town and nation to nation, tunneled mountains of granite, and annihilated space with the lightning's speed. It has whitened the waters of the world with the sails of a hundred nations, navigated every sea and explored every land. It has reduced nature in her thousand forms to as many sciences, taught her laws, prophesied her future movements, measured her untrodden spaces, counted her myriad hosts of worlds, and computed their distances, dimensions, and velocities.
The slow penny is surer than the quick dollar. The slow trotter will out-travel the fleet racer. Genius darts, flutters, and tires; but perseverance wears and wins. The all-day horse wins the race. The afternoon-man wears off the laurels. The last blow drives home the nail.
"Are your discoveries often brilliant intuitions?" asked a reporter of Thomas A. Edison. "Do they come to you while you are lying awake nights?"
"I never did anything worth doing by accident," was the reply, "nor did any of my inventions come indirectly through accident, except the phonograph. No, when I have fully decided that a result is worth getting I go ahead on it and make trial after trial until it comes. I have always kept strictly within the lines of commercially useful inventions. I have never had any time to put on electrical wonders, valuable simply as novelties to catch the popular fancy. I like it," continued the great inventor. "I don't know any other reason. Anything I have begun is always on my mind, and I am not easy while away from it until it is finished."
