Sun Tzu opens with the foundational claim: war is a matter of vital importance to the state, the province of life or death, and therefore deserves study before action. The first chapter is about assessment — before any movement, the commander measures five factors: moral law (whether the cause is just), heaven (climate and timing), earth (terrain), the commander (qualities of leadership), and method and discipline (organization and supply).
These five factors generate seven comparative questions: which ruler has the moral cause, which general the greater ability, which side the advantage of heaven and earth, on which side is discipline enforced, which army is stronger, whose officers and soldiers are better trained, on which side rewards and punishments are most clear.
The deeper move: deception is the foundation of warfare. Appear unable when able, inactive when active, far when near, near when far. The opponent who acts on a false reading of the situation defeats himself.
The practical takeaway, far beyond literal warfare: assess before acting, and shape what the other side sees of you. The commander who can answer the seven questions honestly knows the outcome before the battle.

- Are book summaries actually useful, or am I just cheating?
Chapter summaries are a navigation tool, not a substitute. Used right, they help you read more books fully — by helping you avoid the wrong ones. Used wrong, they're a comfort blanket that lets you feel like you're reading without engaging with the material.

- I read a lot of books but can't remember anything. What works?
