Desire, which is one of the hardest forces to control, will furnish you with excellent exercises in concentration. It seems natural to want to tell others what you know; but, by learning to control these desires, you can wonderfully strengthen your powers of concentration. Remember, you have all you can do to attend to your own business. Do not waste your time in thinking of others or in gossiping about them.
If, from your own observation, you learn something about another person that is detrimental, keep it to yourself. Your opinion may afterwards turn out to be wrong anyway, but whether right or wrong, you have strengthened your will by controlling your desire to communicate your views.
If you hear good news resist the desire to tell it to the first person you meet and you will be benefited thereby. It will require the concentration of all your powers of resistance to prohibit the desire to tell. After you feel that you have complete control over your desires you can then tell your news.
But you must be able to suppress the desire to communicate the news until you are fully ready to tell it. Persons that do not possess this power of control over desires are apt to tell things that they should not, thereby often involving both themselves and others in needless trouble.
If you are in the habit of getting excited when you hear unpleasant news, just control yourself and receive it without any exclamation of surprise. Say to yourself, "Nothing is going to cause me to lose my self-control. You will find from experience that this self-control will be worth much to you in business. You will be looked upon as a cool-headed business man, and this in time becomes a valuable business asset. Of course, circumstances alter cases. At times it is necessary to become enthused. But be ever on the lookout for opportunities for the practice of self-control. "He that ruleth his spirit is greater than he that ruleth a city."
