In the language of sport, you are suffering from a lack of mental "team work." The effect is the same as if the members of a football team, instead of combining their forces against the opposing side, should spend their time in restraining one another. It requires but one step, and not a difficult one at that, to lead you to the conclusion that the solution of this problem lies in having in consciousness at any one moment only such ideas as harmonize. Let that condition prevail, and the potential energies of all ideas in consciousness must flow together in a broad stream of useful and exhilarating activity. [Sidenote: _Rust and the "Daily Grind"_] Your work should be a source of pleasure to you. If it is simply a disagreeable task that has to be performed, if it is a "daily grind," if you have to hold yourself to it by unremitting effort of the will, you are no better than a rusty engine, and all your workings will be accompanied by jars, frictions, and complaining squeaks that bespeak a positively wicked loss of power. Hold the right thoughts persistently in mind, and you cannot help working steadily on toward the goal you are thinking of. Keep steadily at work with the right thoughts persistently in mind and success is sure to come. _Success, then, lies in the concentration of mental energies. And this concentration is to be brought about by holding in consciousness only those ideas that harmonize_. [Sidenote: _Ideas That Harmonize_] There must be the greatest discrimination and care used in the selection of these ideas that are to constitute such a co-ordinating consciousness. There must be a "re-imaging" or imagination in a literal and practical sense of those ideas only that carry with them impulses to motion in the same general direction. You must have a set purpose in life, and you must yield your powers without hindrance and without reservation to the accomplishment of that set purpose. [Sidenote: _Five Rules for Conserving Energy_] I. _You must exercise deliberate, patient and persistent watchfulness to detect and repress all useless bodily movements_. You have all sorts of silly habits, twitchings, jerkings, itchings, winkings, shrugs, frowns, coughs, snifflings and odd and meaningless gestures. Watch yourself. Do these things no more. Save your eyes and ears and hands and nerves, all your mental energy, for useful effort. II. _You must give yourself, mind and body, to one thing at a time, disregarding all that would lure you from your chosen task_.
