This book has for its subject the great principle of Nature known as Desire Power-the Energizing Forces of Nature and of Man. Desire is the Fire or Flame which generates the Steam of Will. If you wish to act with effect and power, and if you wish to have a Strong Will, you must first learn to arouse and to maintain a high degree of Desire Power. This book explains in detail the second element of "The Master Formula," i.e., Insistent Desire, or how to "want hard enough." Very few persons have learned to "want things hard enough"-hence they fail to obtain those things. Insistent Desire is a far different thing from the pale pink "wish" or "want" of the average person. Insistent Desire is like the thirst of a man lost on the desert; the hunger of a starving man; the protective instinct of a tigress with a brood; the mating instinct of the wild animal. This book tells you how to arouse and maintain an Insistent Desire for that which you want and need, and which is requisite for your success and happiness. It shows you how to arouse and maintain in full strength the elemental primordial Desire Force which insistently demands its satisfaction, and which refuses to be denied that which it craves so insistently. It shows you how the Principle of Desire exerts an Attractive Force upon things, persons, circumstances and conditions tending to promote its objects, to further its purposes, to attain its ends. Desire Power "works while you sleep," employing the activities of the Subconscious Mentality in order to work its will and to satisfy its cravings. It shows what happens, and how it happens when you really "want the thing hard enough."
