Summary
Sun Tzu addresses the economics of competition. Raising and maintaining a large force is enormously expensive—not just in money but in exhaustion, morale, and opportunity cost. Extended campaigns drain the treasury, exhaust the people, and invite opportunistic attacks from others. The chapter's key insight: 'There is no instance of a country having benefited from prolonged warfare.' Even victors are weakened by long fights. Therefore, the goal should be quick, decisive victory—or avoiding the engagement entirely. Sun Tzu offers a practical solution for sustained campaigns: use the enemy's resources. Foraging from opponent territory is worth twenty times the equivalent brought from home. Capture equipment rather than destroy it. This principle of leveraging opponent resources transforms a draining competition into a self-sustaining one.

Sun Tzu said: In the operations of war, where there are in the field a thousand swift chariots, as many heavy chariots, and a hundred thousand mail-clad soldiers, with provisions enough to carry them a thousand li, the expenditure at home and at the front... will reach the total of a thousand ounces of silver per day. Such is the cost of raising an army of 100,000 men. Sun Tzu addresses the economics of competition. Raising and maintaining a large force is enormously expensive—not just in money but in exhaustion, morale, and opportunity cost.

Key Quotes & Analysis
"There is no instance of a country having benefited from prolonged warfare."
Context: Warning against extended campaigns that drain resources
Even victory in a prolonged fight leaves you weakened. The winner of a war of attrition is still damaged.
In Today's Words:
Long competitive fights hurt everyone involved—even the 'winner' often loses in the larger picture.
"In war, then, let your great object be victory, not lengthy campaigns."
Context: Emphasizing speed and decisiveness over thoroughness
Efficiency matters more than completeness. A quick win is better than a thorough one that takes too long.
In Today's Words:
Get to the result. A quick 80% victory beats a slow 100% victory.
"Hence a wise general makes a point of foraging on the enemy."
Context: Using opponent resources to sustain your campaign
The genius of using what the opponent has built rather than building your own.
In Today's Words:
Use your competition's investments against them—their talent, their infrastructure, their market awareness.

Critical Thinking Exercise
The Cost of Competition
Identify a competitive situation you're engaged in—for a job, a client, a goal. Calculate its true costs.
Consider:
- •What resources (time, money, energy, relationships) is this competition consuming?
- •How long has it been going on? How much longer might it continue?
- •Is the potential victory worth these ongoing costs?
- •What opponent resources could you leverage instead of building your own?
Journaling Prompt
Describe a competition you should exit, and what you'd gain by redeploying those resources elsewhere.
