Neither is the ancient rule amiss, to bend nature, as a wand, to a contrary extreme, whereby to set it right, understanding it, where the contrary extreme is no vice. Let not a man force a habit upon himself, with a perpetual continuance, but with some intermission. For both the pause reinforceth the new onset; and if a man that is not perfect, be ever in practice, he shall as well practise his errors, as his abilities, and induce one habit of both; and there is no means to help this, but by seasonable intermissions. But let not a man trust his victory over his nature, too far; for nature will lay buried a great time, and yet revive, upon the occasion or temptation. Like as it was with AEsop's damsel, turned from a cat to a woman, who sat very demurely at the board's end, till a mouse ran before her. Therefore, let a man either avoid the occasion altogether; or put himself often to it, that he may be little moved with it. A man's nature is best perceived in privateness, for there is no affectation; in passion, for that putteth a man out of his precepts; and in a new case or experiment, for there custom leaveth him. They are happy men, whose natures sort with their vocations; otherwise they may say, multum incola fuit anima mea; when they converse in those things, they do not affect. In studies, whatsoever a man commandeth upon himself, let him set hours for it; but whatsoever is agreeable to his nature, let him take no care for any set times; for his thoughts will fly to it, of themselves; so as the spaces of other business, or studies, will suffice. A man's nature, runs either to herbs or weeds; therefore let him seasonably water the one, and destroy the other. Of Custom And Education
