If it is possible to make an assault with fire from without, do not wait for it to break out within, but deliver your attack at a favourable moment.

The quote by Sun Tzu emphasizes the importance of proactive strategies in conflict and decision-making. It suggests that if an external opportunity presents itself, especially one that can disrupt an opponent or adversary, one should act decisively rather than waiting for circumstances to become unfavorable or for the threat to manifest internally. In essence, Sun Tzu advocates for preemptive action and leveraging favorable conditions to achieve success. This wisdom transcends its military origins and can be effectively applied in various modern contexts, such as business, personal development, and even interpersonal relationships. For instance, in the business world, if a company identifies an emerging market trend or a competitor's weakness, it is prudent for them to act quickly—be it through innovation, strategic marketing, or a competitive pricing strategy—rather than waiting for the competition to adjust or counteract. This proactive approach can secure a strong market position or foster growth in otherwise challenging environments. In personal or professional relationships, the advice can be seen as a call to address potential conflicts before they escalate. If one senses tension brewing or underlying issues surfacing within a team or partnership, it is often wise to initiate a dialogue or seek resolution rather than letting frustration or misunderstanding fester. Overall, Sun Tzu's quote promotes foresight and action. It underlines the principle that waiting for problems to evolve can be detrimental, and instead, one should seize opportunities for intervention when conditions are favorable. In today's fast-paced and competitive world, acting decisively in the face of potential challenges or openings can often determine long-term success.
