LAW NO.23 — CONCENTRATE YOUR FORCES:
The story of Wu is a paradigm of all the empires that have come to ruin by overreaching. Drunk with success and sick with ambition…serves as an elemental lesson on what happens when you dissipate your forces on several fronts, losing sight of distant dangers for the sake of present gain. “If you are not in danger,” says Sun-tzu, “do not fight.” It is almost a physical law: What is bloated beyond its proportions inevitably collapses. The mind must not wander from goal to goal, or be distracted by success from its sense of purpose and proportion. What is concentrated, coherent, and connected to its past has power. What is dissipated, divided, and distended rots and falls to the ground. The bigger it bloats, the harder it falls.
–Robert Greene, The 48 Laws of Power
