《商君书·说民》
国家用难以获得的实力去攻打其他国家，用一分力量能取得十分效果；国家用容易得到的空谈去攻打其他国家，用一分力量会损失百倍的力量。
国以难攻，起一取十，国以易攻，起十亡百。
The state uses hard-won strength to attack other countries, and uses one-tenth of its strength to achieve results; the state uses readily available rhetoric to attack other countries, and uses one-tenth of its strength to lose a hundred times its strength.
