Sun Tzu on Decision-Making
The Art of War is a manual for decisions under uncertainty. Its method — information first, calculation next, commitment only when the conditions are right — applies far beyond the battlefield.
Decide from knowledge, not hope
Sun Tzu’s five factors are a pre-decision checklist. The habit of estimating before acting replaces guesswork with a defensible judgment.
Commit when the moment is real
He separates preparation (yours to control) from the enemy’s mistake (yours to exploit). Apply it by acting only when the opening is real, not to feel busy.
