Weariness, exhaustion even, is no excuse.  If you are tired, take a rest.  If your natural energy is not equal to your task, take a lesser task.  There is nothing more melancholy than the spectacle of men, young or old, attempting things out of proportion to themselves.  It is hard to gage what is beyond one’s natural powers, it is true.  But if you feel the need of stimulants to keep you up to the level of your work, that is at least one unfailing test of your limitations.  I must repeat, for the third time, that all of this advice—­no, let us say suggestion—­is made only as a matter of practical help to young men trying to get on in the world.

It is the mere business side of the question at which we are looking now, for it is business itself that is working this change.  People do not want a lawyer whose brain is not clear, a doctor, dealing with life and death, whose perceptions are not steady and natural.  People refuse to ride on trains hauled by engineers who may be drinking, and so on.  It is all a matter of cold-blooded business.

The conditions and requirements of modern society are coming to demand greater and greater sobriety from those in responsible places, no matter whether at the head of a party or a railway train.  The spiritual phase, the medical view, the moral, social, and economic sides of the question I would not, under any circumstances, assume to deal with.  On all these there are various views, none of which would I undertake to weigh or judge.

And excessive talking!  Don’t indulge in that either.  Politicians are not the only ones who think interminable talk an indication of weakness.  I knew a liveryman who was also a great horse-trader.  Said he:  “I shy clear across the road when a tonguey man tries to deal with me.”

Of course, reserve in speech, particularly in conversation, is so ancient and favorite a subject of the giver of advice that it is now commonplace.  Literature is full of it.  Shakespeare nearly reaches the crest of it in the advice Polonius gave to his son.  But here, as always, the very climax is the Bible.

“Let your communication be Yea, yea; Nay, nay; for whatsoever is more than these cometh of evil.”

This is not advice to taciturnity.  It is not a suggestion that you should be stolid and wooden in manner and speech.  The reason of it is to prevent you from making mistakes or betraying yourself by foolish and unnecessary utterance.  My suggestion to young men that they practise reserve in speech is merely a practical and almost a commercial matter.  Do not be “a man full of talk,” as Zophar cuttingly puts it.

There is a loss of authority that comes from incessant talking.  There is a surrender of dignity, which is one of the most influential things in man’s attitude toward and in connection with his fellows.  Silence, or rather reserve, gives a kind of emphasis to what you do.  To a great many, also, there is an index of your character in the quantity of your speech.  It is so refreshing to meet a man from whom you draw the feeling that he is as deep and as full as the seven seas.
