              accomplish just so much work in a given time, and continue to labor
            
            
              when their judgment tells them they should rest, are never gainers.
            
            
              They are living on borrowed capital. They are expending the vital
            
            
              force which they will need at a future time. And when the energy
            
            
              they have so recklessly used is demanded, they fail for want of it.
            
            
              The physical strength is gone, the mental powers fail. They realize
            
            
              that they have met with a loss, but do not know what it is. Their time
            
            
              of need has come, but their physical resources are exhausted.
            
            
              Everyone who violates the laws of health must sometime be
            
            
              a sufferer to a greater or less degree. God has provided us with
            
            
              constitutional force, which will be needed at different periods of our
            
            
              lives. If we recklessly exhaust this force by continual overtaxation,
            
            
              we shall sometimes be losers. Our usefulness will be lessened, if

              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.—

              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

              powers to engage in the work which the Lord has appointed him in

              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
