Begin, too, with a determination to labor through life. There are many who suppose that when they have secured to themselves a competence, they shall sit with folded arms, in an easy chair, the rest of their days, and enjoy it. But they may be assured that this will never do. The very fact of a person's having spent the early and middle part of life in active usefulness, creates a necessity, to the body and mind, of its continuance. By this is not meant that men should labor as _hard_ in old age, even in proportion to their strength, as in early life. Youth requires a great variety and amount of action, maturity not so much, and age still less. Yet so much as age does, in fact, demand, is more necessary than to those who are younger. Children are so tenacious of life, that they do not _appear_ to _suffer immediately_, if exercise is neglected; though a day of reckoning must finally come. Hence we see the reason why those who retire from business towards the close of life, so often become diseased, in body and mind; and instead of enjoying life, or making those around them happy, become a source of misery to themselves and others. Most people have a general belief in the importance of industrious habits; and yet not a few make strange work in endeavoring to form them. Some attempt to do it by compulsion; others by flattery. Some think it is to be accomplished by set lessons, in spite of example; others by example alone. A certain father who was deeply convinced of the importance of forming his sons to habits of industry, used to employ them whole days in removing and replacing heaps of stones. This was well intended, and arose from regarding industry as a high accomplishment; but there is some danger of defeating our own purpose in this way, and of producing _disgust_. Besides this, labor enough can usually be obtained which is obviously profitable. All persons, without exception, ought to labor more or less, every day in the open air. Of the truth of this opinion, the public are beginning to be sensible; and hence we hear much said, lately, about manual labor schools. Those who, from particular circumstances, cannot labor in the open air, should substitute in its place some active mechanical employment, together with suitable calisthenic or gymnastic exercises. It is a great misfortune of the present day, that almost every one is, by his own estimate, _raised above his real state of life_. Nearly every person you meet with is aiming at a situation in which he shall be exempted from the drudgery of laboring with his hands.
