Evening Labor—As a rule, the labor of the day should not be prolonged into the evening.... I have been shown that those who do this, often lose much more than they gain, for their energies are exhausted, and they labor on nervous excitement. They may not realize any immediate injury, but they are surely undermining their constitution.—Counsels on Health, 99. (Te 140.1) MC VC

Temperance in Study—Intemperance in study is a species of intoxication, and those who indulge in it, like the drunkard, wander from safe paths, and stumble and fall in the darkness. The Lord would have every student bear in mind that the eye must be kept single to the glory of God. He is not to exhaust and waste his physical and mental powers in seeking to acquire all possible knowledge of the sciences, but is to preserve the freshness and vigor of all his powers to engage in the work which the Lord has appointed him in helping souls to find the path of righteousness.—Counsels to Parents, Teachers, and Students, 405, 406. (Te 140.2) MC VC

Intemperance in Seeking Riches—One of the most fruitful sources of shattered constitutions among men is a devotion to the getting of money, an inordinate desire for wealth. They narrow their lives to the single pursuit of money, sacrifice rest, sleep, and the comforts of life to this one object. Their naturally good constitutions are broken down, disease sets in as a consequence of the abuse of their physical powers, and death closes the scene of a perverted life. Not a dollar of his wealth can that man take with him who has obtained it at such a terrible price. Money, palaces, and rich apparel avail him nothing now; his lifework is worse than useless.—The Health Reformer, April, 1877. (Te 140.3) MC VC

To Guard Every Fiber of the Being—Every organ, every fiber of the being, is to be sacredly guarded from every harmful practice, if we would not be among the number that Christ represents as walking in the same dishonorable path as did the inhabitants of the world before the Flood. Those in this number will be appointed to destruction, because they have persisted in carrying lawful habits to extremes, and have created and indulged habits that have no foundation in nature, and that become a warring lust.... (Te 140.4) MC VC
