If opportunities do not fortuitously occur, then the man of earnest purpose proceeds to make them for himself. He looks for helps every where; there are many roads into Nature; and if determined to find a path, a man need not have to wait long. He turns all accidents to account, and makes them promote his purpose. Dr. Lee, professor of Hebrew at Cambridge, pursued his trade of a bricklayer up to twenty-eight years of age, and was first led to study Hebrew by becoming interested in a Hebrew Bible, which fell in his way when engaged in the repairs of a synagogue; but before this time he had been engaged in the culture of his intellect, devoting all his spare hours and much of his nights to the study of Latin and Greek. Ferguson, the astronomer, cultivated the opportunity afforded him by the nights occupied by him in watching the flocks on the Highland hills, of studying astronomy in the heavens; and the sheep-skin in which he wrapped himself, became him as well as the gown of the Oxford Professor. Osgood, the American painter, when a boy, was deprived by an austere relative, of the use of pencils and paper; but he set to work and practiced drawing on the sand of the river side. Gifford, late editor of the _Quarterly Review_, worked his first problems in mathematics, when a cobbler's apprentice, upon small scraps of leather, which he beat smooth for the purpose. Bloomfield, the author of the "Farmer's Boy," wrote his first poems on the same material with an awl. Bewick first practiced his genius on the cottage-walls of his native village, which he covered with his sketches in chalk. Rittenhouse, the astronomer, calculated eclipses on the plow-handle. Benjamin West, the painter, made his first brushes out of the cat's tail. It is not accident, then, that helps a man on in the world, but purpose and persistent industry. These make a man sharp to discern opportunities, and to use them. To the sluggish and the purposeless, the happiest opportunities avail nothing--they pass them by with indifference, seeing no meaning in them. Successful men achieve and perform, because they have the purpose to do so. They "scorn delights, and live laborious days." They labor with hand and head. Difficulties serve only to draw forth the energies of their character, and often their highest pleasure is in grappling with and overcoming them. Difficulties are the tutors and monitors of men, placed in their path for their best discipline and development. Push through, then strength will grow with repeated effort.
