Sun Tzu's Art of War, Chapter 8, emphasizes adaptable strategies ("nine variations") based on terrain and circumstances. It stresses careful consideration of advantages and disadvantages, advising against rash actions and highlighting the importance of preparedness. The text details methods for influencing allies and rivals, while also warning against five dangerous leadership traits—recklessness, cowardice, impatience, excessive scrupulousness, and excessive compassion—that can lead to military defeat. Ultimately, success hinges on understanding terrain, adapting to changing conditions, and avoiding leadership flaws.
