It is an old trick of despots, and a good one, to employ their subjects. Why? To keep them out of mischief, Employed men are most contented. There is no conspiracy. Men do not sit down and coolly proceed to concoct iniquity so long as there is plenty of pleasant and profitable employment for body and mind. Work drives off discontent, provided there is compensation in proportion to the amount of labor performed. There must be a stimulant. God never intended a man should sweat without eating of the fruits of his labor - reaping a reward - more than he intended the idle man should revel in plenty and grow gouty on luxuries. Industry is a great peacemaker - a mind-your-own-business citizen. Something to do renders the despairing good-natured and hopeful - stops the cry of the hungry, and promotes all virtue. The best men are the most industrious; the most wealthy work the hardest. They always find something to do. Do you ever wonder that men of wealth do not "retire" and enjoy their substance? We know some young men look forward with anticipation to the time of "retiring." It is doubtful if a man should ever retire from business as long as he lives. We think we know men who, were they to abandon business, would be ruined, not pecuniarily, but mentally - their lives would be shortened. God never intended man's mind should become dormant. It is governed by fixed laws. Those laws are imperative in their exactions.
Something to do! "Oh, if I had something to do!" There are young men who sigh for it, yet one thing they can do - that is, seek for a job. Once found, provided it is an honest one, do not hesitate to perform it, even if it does not pay as well as you expected.
