If you must smoke, smoke moderately.
Shun discussion on two points—religion and politics.
And last, but not least, marry a true woman, and have your own home.

HIS SOCIAL LIFE AND AMUSEMENTS
HE social life of a young man has a direct and important bearing upon his success, and he cannot be too careful of what forms of amusement he allows to come into his hours of leisure.
From a business standpoint it is all-important that he keep a careful watch on his social habits. For it is not enough for any young man that he should only take care of himself during his working-hours. To social dissipations at night can be traced the downfall of hundreds upon hundreds of young men. The idea that an employer has no control over a young man's time away from the office is a dangerous fallacy. An employer has every right to ask that those into whose hands he intrusts responsibilities shall follow social habits which will not endanger his interests upon the morrow. So far as social life is concerned, young men generally run to extremes. Either they do not go out at all, which is stagnating, or they go out too much, which is deadly. Only here and there is found one who knows the happy medium; a certain amount of social diversion is essential to everybody—boy, man, girl, or woman; and particularly so to a young man with a career to make. To come into contact with the social side of people is broadening; it is educative. "To know people," says a writer, "you must see them at play." Social life can be made a study at the same time that it is made a pleasure. To know the wants of people, to learn their softer side, you must come into contact with their social natures. No young man can afford to deny himself certain pleasures, or a reasonable amount of contact with people in the outer world. It is to his advantage that people should know he exists; it is important to the wise shaping of his aims and aspirations. It is well for him to keep himself honorably in the eyes of people. His evening diversions should be as widely different from his occupations during the day as possible. The mind needs a change of thought as well as does the body a change of raiment. "All work and no play makes Jack a dull boy" contains a vast amount of truth.
At the same time, nothing is more injurious to the chances of a young man in business than an over-indulgence in the pleasures of what, for the want of a better word, we call "society." It is a rough but a true saying that "a man cannot drink whisky and be in business." Perhaps a softer and more refined translation of this is that a man cannot be in society and be in business. This is impossible, and nothing that a young man can bear in mind will stand him to such good account as this fact. No mind can be fresh in the morning that has been kept at a tension the night before by late hours, or been befogged by indulgence in late suppers. We need more sleep at twenty or twenty-five than we do at fifty; and the young man who grants himself less than eight hours' sleep every night just robs himself of so much vitality. So far as the required amount of sleeping is concerned, I hold to this inexorable rule: sleep eight hours every night and an extra hour whenever possible. The most successful men have repeatedly acknowledged that to a regularity in hours of retiring they can trace a large part of their ability to compass the questions which enter into a successful career.
