War and trade have accompanied our ancestors since ancient times. There was no significant difference between these types of human activities. The warrior was engaged in trade, and the merchant was often a warrior. There are no untested or ill-conceived methods in war. Every step, every action is clearly outlined, because the stakes are too high. Ancient scientists wrote entire treatises on the topic of war. They taught how to achieve victory on the battlefield with minimal losses. War and business are very similar. In both of these areas there are winners and losers, there are victories and defeats, there are attacks and negotiations, pressure and persuasion. The "businessmen" of the ancient world used the art of warfare to develop trade. But for some reason our contemporaries do not favor military knowledge at all. Maybe because the most famous treatise on the art of war, written back in the 3rd–5th centuries BC by the Chinese commander Sun Tzu, was banned in the USSR and could only be used by special services? The book will introduce you to this ancient teaching, tell you how the great ancient techniques of warfare can be used in modern business; how to build negotiations to change partners’ beliefs; what qualities of a commander should a businessman possess. But you can answer: “I’m not interested in this, I’m not a businessman.” Take your time. If you think about it, each of us, no matter what type of activity we engage in, has to conclude certain deals, therefore, promote our ideas by changing the beliefs of our interlocutors, partners, friends, family members. This book will teach you how to achieve success in career, how to improve family relationships, influence people, changing their ideals, and, of course, it is indispensable for businessmen!
