A course not unlike that which I have been describing, faithfully and perseveringly followed, would in nine cases in ten, be successful. Indeed, I never yet knew of a single failure. One great point is, to be thoroughly convinced of its importance. No young man can reasonably expect success, unless he enters upon his work with his whole heart, and pursues it with untiring assiduity. Of the _necessity_ of improvement, very few young men seem to have doubts. But there is a difficulty which many feel, which it will require no little effort to remove, because it is one of long standing, and wrought into all the arrangements of civilized society. I allude to the prevailing impression that very little can be done to improve the mind beyond a certain age, and the limit is often fixed at eighteen or twenty years. We hear it, indeed, asserted, that nothing can be done after thirty; but the general belief is that most men cannot do much after twenty: or at least that it will cost much harder effort and study. Now, I would be the last to encourage any young person in wasting, or even undervaluing his early years; for youth is a golden period, and every moment well spent will be to the future what good seed, well planted in its season, is to the husbandman. The truth is, that what we commonly call a course of education, is only a course which prepares a young man to educate himself. It is giving him the keys of knowledge. But who will sit down contentedly and cease to make effort, the moment he obtains the keys to the most valuable of treasures? It is strange, indeed, that we should so long have talked of finishing an education, when we have only just prepared ourselves to begin it. If any young man at twenty, twenty-five, or thirty, finds himself ignorant, whether the fault is his own or that of others, let him not for one single moment regard his age as presenting a serious obstacle to improvement. Should these remarks meet the eye of any such individual, let me prevail with him, when I urge him to make an effort. Not a momentary effort, either; let him _take time_ for his experiment. Even Rome was not built in a day; and he who thinks to build up a well regulated and highly enlightened mind in a few weeks, or even months, has yet to learn the depths of his own ignorance. It would be easy to cite a long list of men who commenced study late in life, and yet finally became eminent; and this, too, with no instructors but themselves and their books. Some have met with signal success, who commenced after forty years of age. Indeed, no reason can be shown, why the mind may not improve as long, at least, as the body. But all experience goes to prove that with those whose habits are judicious, the physical frame does not attain perfection, in every respect, till thirty-five or forty.
