Right in line with this phase of a young man's work comes the necessity of his learning that he cannot do evening work and be employed the entire day as well. It is the most difficult thing for ambitious young men to understand that night-work is physically and mentally detrimental to the best business success. Let a machine run night and day, and before long it will break down; and what a mechanism of iron and steel cannot bear, the human organism certainly cannot stand. If a young man employs his evenings for work, he unfits himself for his work during the day. The mind needs diversion, recreation, rest; and any mentality kept at a certain tension for more than seven or eight hours per day will sooner or later lose its keen perceptive powers. No young man true to his best and wisest interests will employ his evenings in the same line of thought as that which engrosses him during the day. Mental work is unlike manual labor in that it tires without physical exhaustion; and because the worker does not feel it as much when he uses his head for ten or twelve hours per day as he would if he used the muscles for that period of time, he goes, nevertheless, unconsciously beyond his powers of strength. Unknown to him, the strain leaves its mark upon the mind. Youthful vigor throws its effects off for a while, but not permanently; and a man's early breakdown when he should be at the zenith of his powers in middle life is very often directly traceable to an overtaxing of his powers in early life. But not only is the effect of a future character; it is noticeable at the time of the indiscretion. It is seen in the inability of the mind to respond quickly to some suggestion at the office; and how can it be otherwise when the mind has been worked beyond its normal capacity? There is no question in my mind whatever that a young man is untrue to the interests of his employer when he allows himself to work during the evening hours. Although he may not be conscious of it himself, he does not come to his work the following morning as fresh as he might if the mind had been given a season of diversion and rest.

I know whereof I speak when I touch upon this subject. In common with other young men who are wiser than their best advisers, I made the mistake of evening work. For several years I gave up four or five evenings of each week to literary work. My family, my best friends, my physician, warned me to desist. But I knew better. Others, I conceded, undoubtedly had suffered from what I was doing, but I should not. I was strong, young, and of excellent physique. I could stand it; others could not; in fact, I was an exception to the rest of the human race. Two or three years went by, and I was proud of proving to my advisers that I was right and they were wrong. But suddenly, with scarce a warning, the blow came. Irritability and nervousness came first; everything annoyed me. The closing of a door, or the sudden entrance of a person into the room, caused me to start. The harder I worked the less I seemed to accomplish. I could not understand it. Then I began to lie awake for a half-hour after I retired; after a while the half-hour lengthened into an hour, then into two hours. Finally I had insomnia. After a bit my digestion did not seem to be as regular; a heavy feeling possessed me after eating. I was ordered away; stayed a week when I was told I should remain for a month. But, of course, I knew better. And what is the result? For the past three years I have suffered from an indigestion as constant as it is keen; and to-day I have to regulate my food, my hours, and my habits, with the pleasing prospect that at least two years of such living are ahead of me before I can hope for relief. And why? Simply because of working, years ago, when I should have been resting. But then I did not understand it. I do now, and I wish that every young man who reads these words might profit by my error. I am fortunate to get off with nothing more serious than indigestion, but even that affliction has pains which only those who have suffered them can begin to fully realize. Night-work, when employed in the day, does not pay; on the contrary, it kills. I wish fervently and sincerely that five, eight, or ten years ago I might have reached this point of wisdom. I did not, but I write it now and here as a warning to young fellows who value their health, their happiness, their peace of mind, and a comfortable feeling in the pits of their stomachs.

A fatal error in the case of many young men is that they reach a point where they make no progress. Now stagnation in a young man's career is but a synonym for starvation, since there is no such thing as standing still in the business world of to-day. Either we go backward or we go forward. When a young man fails to keep abreast of the possibilities of his position he recedes constantly, if unconsciously, perhaps. The young man who progresses is he who enters into the spirit of the business of his employer, and who points out new methods to him, advances new ideas, suggests new channels and outputs. There is not a more direct road to the confidence of an employer than for that employer to see that any one of his clerks understands the details of his business better than himself. That young man commands the attention of his chief at once, and when a vacancy occurs he is apt to step into it, if he does not forge over the shoulders of others. Young men who think clearly, who can conceive, create, and carry out, are not so plentiful that even a single one will be lost sight of. It is no special art, and it reflects but little credit upon any man, to simply fill a position. That is expected of him; he is engaged to do that, and it is only a fair return for a certain payment made. The art lies in doing more than was bargained for; in proving greater than was expected; in making more of a position than has ever been made before. A quick conception is needed here, the ability to view a broad horizon; for it is the liberal-minded man, not the man of narrow limitations, who makes the success of to-day. A young man showing such qualities to an employer does not remain in one position long.

Two traps in which young men in business often fall are a disregard for small things, and an absolute fear of making mistakes. One of the surest keys to success lies in thoroughness. No matter how great may be the enterprise undertaken, a regard for the small things is necessary. Just as the little courtesies of every-day life make life worth the living, so the little details form the bone and sinew of a great success. A thing half or three-quarters done is worse than not done at all. Let a man be careful of the small things in business, and he can generally be relied upon for the greater ones, provided, of course, that he possesses broadness of mind. The man who can overcome small worries is greater than the man who can override great obstacles. When a young man becomes so ambitious for large success that he overlooks the small things, he is pretty apt to encounter failure. There is nothing in business so infinitesimal that we can afford to do it in a slipshod fashion. It is no art to answer twenty letters in a morning when they are, in reality, only half answered. When we commend brevity in business letters we do not mean brusqueness. Nothing stamps the character of a house so clearly as the letters it sends out.

The fear of making mistakes keeps many a young man down. Of course errors in business are costly, and it is better not to make them. But, at the same time, I would not give a snap of the finger for a young man who has never made mistakes. But there are mistakes and mistakes; some easy to be overlooked, and others it is better not to blink at in an employee. A mistake of judgment is possible with us all; the best of us are not above a wrong decision. And a young man who holds back for fear of making mistakes loses the first point of success.

I know there are thousands of young men who feel themselves incompetent for a business career because of a lack of early education. And here might come in—if I chose to discuss the subject, which I do not—the oft-mooted question of the exact value of a college education to the young man in business. Far abler pens than mine have treated of this; it is certainly not for me to enter into it here. But I will say this: a young man need not feel that the lack of a college education will stand in any respect whatever in the way of his success in the business world. No college on earth ever made a business man. The knowledge acquired in college has fitted thousands of men for professional success, but it has also unfitted other thousands for a practical business career. A college training is never wasted, although I have seen again and again five-thousand-dollar educations spent on five-hundred-dollar men. Where a young man can bring a college education to the requirements of a practical business knowledge it is an advantage. But before our American colleges become an absolute factor in the business capacities of men, their methods of study and learning will have to be radically changed. I have had associated with me both kinds of young men, collegiate and non-collegiate, and I must confess that the ones who had a better knowledge of the practical part of life have been those who never saw the inside of a college and whose feet never stood upon a campus. College-bred men and men who never had college advantages have succeeded in about equal ratios. The men occupying the most important commercial positions in New York to-day are self-made, whose only education has come to them from contact with that greatest college of all, the business world. Far be it from me to depreciate the value of a college education. I believe in its advantages too firmly. But no young man need feel hampered because of the lack of it. If business qualities are in him they will come to the surface. It is not the college education; it is the young man. Without its possession as great and honorable successes have been made as with it. Men are not accepted in the business world upon their collegiate diplomas, nor on the knowledge these imply. They are taken for what they are, for what they know.

The young man engaged in business to-day in this country has advantages exceeding those of any generation before him. And I do not say this simply as an echo of what others before me have said, or to use a platitudinous phrase. There never was a time in the world's history when a young man had the opportunity to make something of himself that he has at the present day. He lives in a country where every success is possible; where a man can make of himself what he may choose; where energy and enterprise are appreciated, and a market is always ready for good wares. Young men have forged to the front wonderfully during the past ten years. Employers are more than ever willing to lay great responsibilities on their shoulders. Salaries are higher than ever; young men never before earned the incomes which are received by some to-day. All success is possible.

But a young man must be alert to every opportunity. He cannot forget himself for a moment in business. A man's best working years are not many, and when they are upon him he must make hay, and all the hay he can. No young man can afford to reach the age of thirty without feeling that he is settled in a business way. Before that time he flounders; but at thirty the floundering time should be over. He should have found that special trade or profession for which he thinks he is most capable. This age is generally accepted, I believe, for the reason that a man is most likely to do his best work between thirty and forty; after forty a man's work is not apt to have that energy and snap that is born of youth, and the tendency is first shown in his willingness to deputize details to others. I do not mean to say that a man begins to decline at forty; on the contrary, he is at his prime, and he remains so for ten or fifteen years. But he is better for judgment than he is for working out details. A man's real work, his energetic work, his laborious work, is generally done before he reaches thirty-five.

And not only must he practically make himself between thirty and forty, but he must not spend all that he earns. He must lay aside a goodly portion of his earnings. It is a cruel but a hard fact that the business world has very little use for what are termed old men nowadays; and in these times of keen competitive strife a man is judged to be old very early from the cold commercial point of view. He may not consider himself as being old, but he is no longer considered to be "in the race" with the younger men, who naturally have quicker perceptions and whose sense of alertness is necessarily keener. The most successful man at forty is very often the man who is quietly pushed aside at sixty. If young men earning good incomes between thirty and forty would look a little ahead, and consider the inevitable fact that as they grow older their value is very apt to lessen in a commercial sense, they would save themselves much after-humiliation and sorrowful retrospection. It is hard for a young man at, say, thirty-five, in the full flush and vigor of manhood, to realize that a time will come when others as clever as himself and a bit cleverer will pass him by. But the cold fact exists, nevertheless, and he is wise who, at his prime, thinks of a time which is almost sure to come to every man who lives.

And yet, while a young man may be ambitious for success in business, he cannot afford to get impatient or restless. Not long ago I received a letter from a young fellow which particularly reflected the feeling that I mean. He wrote me that he was twenty, and was impatient because he did not make the progress in his business which he felt that he should. He confessed that he was not so very much dissatisfied with his salary, which was twenty-two dollars per week, although he thought it ought to be forty dollars. Unfortunately for him, however, his employers did not seem to think so, and he was quite sure he was "being kept back." He conceded that he was "becoming impatient," but insisted that he had reason to feel so.
