Every idea that memory thrusts into your consciousness carries with it the impulse to act upon it. If you fail to do so, the matter may not again occur to you, or when it does it may be too late.
Your mental mechanism will serve you faithfully only as long as you act upon its suggestions.
This is as true of bodily habits as of business affairs. The time to act upon an important matter that just now comes to mind is not "tomorrow" or a "little later," but NOW.
What you do from moment to moment tells the story of your career. Ideas that come to you should be compared as to their relative importance. But do this honestly. Do not be swayed by distracting impulses that inadvertently slip in. And having gauged their importance give free rein at once to the impulse to do everything that should not make way for something more important.
If, for any reason, action must be deferred, fix the matter in your mind to be called up at the proper time. Drive all other thoughts from your consciousness. Give your whole attention to this one matter. Determine the exact moment at which you wish it to be recalled. Then put your whole self into the determination to remember it at precisely the right moment. And finally, and perhaps most important of all.
