Sun Tzu lays out the doctrine of adaptive command. The general who can vary tactics according to the situation has understood the use of an army; the one who cannot is its prisoner. Five faults of generals are named: recklessness leading to destruction, cowardice leading to capture, hasty temper leading to provocation, delicacy of honor leading to shame, over-solicitude for troops leading to worry.
Each fault is a failure to vary — the inability to set aside a personal disposition when the situation demands the opposite. Bravery has a time to defer; caution has a time to risk. Personal honor is sometimes the cost of victory; sometimes the cost is worth paying.
The chapter is about flexibility as a competence, not as weakness. The general who can do only one thing well is mastered by an enemy who can present many situations. The general who can change is mastered by no one.
The civilian translation: identify the disposition you default to under pressure — boldness, caution, conciliation, attack — and practice the opposite. The version of you that can do both is the version that wins more contests.

- 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?
