This book in my hands represents the culmination of Sun Tzu’s rich military experience as the commander of the Chinese Imperial army. He wrote this book to establish rules that are essential for any commander, in order to ensure victory in the best possible ways, and to minimize losses and avoid devastating defeats in the most difficult situations. As the Chinese philosopher said, strength alone is not enough; intelligence and knowledge can also determine the fate of an entire army. These rules, reflecting his profound wisdom and experience, are essentially the first written military treatise, and they have been used for thousands of years. Their effectiveness in countless battles is undoubtedly a testament to their value. But what if we had enough intelligence to apply these principles to our own lives, and try to implement them in our daily reality? In an era where life itself has become a war, we truly need such a book to guide us along the shortest and most intelligent paths to survival in our daily battles.
