Concentration is the secret of strength in politics, in war, in trade, in short, in all management of human affairs. One of the high anecdotes of the world is the reply of Newton to the inquiry, "how he had been able to achieve his discoveries?" —"By always intending my mind." Or if you will have a text from politics, take this from Plutarch: "There was, in the whole city, but one street in which Pericles was ever seen, the street which led to the market-place and the council house. He declined all invitations to banquets, and all gay assemblies and company. During the whole period of his administration, he never dined at the table of a friend." Or if we seek an example from trade,— "I hope," said a good man to Rothschild, "your children are not too fond of money and business: I am sure you would not wish that." —"I am sure I should wish that: I wish them to give mind, soul, heart, and body to business, —that is the way to be happy. It requires a great deal of boldness and a great deal of caution, to make a great fortune, and when you have got it, it requires ten times as much wit to keep it. If I were to listen to all the projects proposed to me, I should ruin myself very soon. Stick to one business, young man. Stick to your brewery, (he said this to young Buxton,) and you will be the great brewer of London. Be brewer, and banker, and merchant, and manufacturer, and you will soon be in the Gazette." Many men are knowing, many are apprehensive and tenacious, but they do not rush to a decision. But in our flowing affairs a decision must be made, —the best, if you can; but any is better than none. There are twenty ways of going to a point, and one is the shortest; but set out at once on one. A man who has that presence of mind which can bring to him on the instant all he knows, is worth for action a dozen men who know as much, but can only bring it to light slowly. ... The good Speaker in the House is not the man who knows the theory of parliamentary tactics, but the man who decides off-hand. The good judge is not he who does hair-splitting justice to every allegation, but who, aiming at substantial justice, rules something intelligible for the guidance of suitors. The good lawyer is not the man who has an eye to every side and angle of contingency, and qualifies all his qualifications, but who throws himself on your part so heartily, that he can get you out of a scrape.
Dr. Johnson said, in one of his flowing sentences, "Miserable beyond all names of wretchedness is that unhappy pair, who are doomed to reduce beforehand to the principles of abstract reason all the details of each domestic day. There are cases where little can be said, and much must be done."
