Fifth, let him remember that a young man's strongest recommendation is his respectability. Some young men, apparently successful, may be flashy in dress, loud in manner, and disrespectful of women and sacred things. But the young man who is respectable always wears best. The way a young man carries himself in his private life ofttimes means much to him in his business career. No matter where he is, or in whose company, respectability, and all that it implies, will always command respect.
And if any young man wishes a set of rules even more concise, here it is:
Get into a business you like.
Devote yourself to it.
Be honest in everything.
Employ caution; think out a thing well before you enter upon it.
Sleep eight hours every night.
Do everything that means keeping in good health.
School yourself not to worry; worry kills, work does not.
Avoid liquors of all kinds.
