Original Text(~173 words)
Sun Tzu said: Whoever is first in the field and awaits the coming of the enemy, will be fresh for the fight; whoever is second in the field and has to hasten to battle will arrive exhausted. Therefore the clever combatant imposes his will on the enemy, but does not allow the enemy's will to be imposed on him. This chapter is about attack selection and adaptability. The skilled strategist chooses where and when to engage, attacking weaknesses rather than strengths. They impose their will rather than reacting to the enemy's. Sun Tzu emphasizes speed and first-mover positioning. Whoever arrives first controls the terrain; whoever arrives second is already at disadvantage. The skilled general 'marches swiftly to places where he is not expected.' The chapter's most famous passage describes water: 'Water shapes its course according to the nature of the ground over which it flows.' The successful strategist is similarly adaptable—formless, responding to circumstances rather than following rigid plans. There are no fixed tactics; everything depends on reading and responding to the situation.

Key Quotes & Analysis
"The clever combatant imposes his will on the enemy, but does not allow the enemy's will to be imposed on him."
Context: The essence of strategic initiative
Dictating terms is decisive advantage. Reacting to others' terms is already losing.
In Today's Words:
Set the agenda. If you're just responding to what they do, you've already lost the initiative.
"Water shapes its course according to the nature of the ground over which it flows; the soldier works out his victory in relation to the foe whom he is facing."
Context: Teaching adaptability through the metaphor of water
Rigid tactics fail. Successful strategy adapts to circumstances.
In Today's Words:
Don't follow a fixed playbook. Adapt to what's actually in front of you.
"Military tactics are like unto water; for water in its natural course runs away from high places and hastens downwards. So in war, the way is to avoid what is strong and to strike at what is weak."
Context: Explaining attack selection through natural metaphor
Attack weakness, not strength. Like water finding the path of least resistance.
In Today's Words:
Don't attack where they're strong. Find the gap, the weakness, the undefended point.

The Market Entry
Following Maya's story...
Maya's startup is considering entering the small business accounting software market. The obvious competitors are giants—established, well-funded, feature-rich. Competing head-on would be suicide. Maya applies Sun Tzu's water principle. Where are the giants weak? She discovers: enterprise-focused giants neglect very small businesses (too small to be profitable). They underserve specific industries with unique needs. Their customer support is impersonal. Their products are complex. Maya doesn't compete where they're strong. She attacks where they're weak: micro-businesses, a specific underserved industry, with white-glove onboarding and radically simplified interface. By the time the giants notice, she owns the niche. 'Strike at what is weak, avoid what is strong.' Maya flows around the rocks rather than fighting them.

Amplification
The winner isn't who's strongest overall—it's who concentrates strength against weakness.
