Shaping the enemy's actions
Miyamoto Musashi offers a subtle rule. The important thing in strategy is to suppress the enemy’s useful actions but allow his useless actions. In other words, do not try to block everything. Focus on stopping what truly threatens you, and let your opponent waste energy elsewhere.
This is a lesson in economy. Fighting every move exhausts you quickly. By contrast, letting harmless actions pass conserves strength for the moments that matter. Skilled negotiators, athletes and chess players all work this way. They choose their battles carefully.
Applying the idea of the enemy's actions in business
Competition in markets follows similar logic. A company does not need to answer every competitor campaign. Instead, it should identify the moves that genuinely threaten its customers or margins. For example, a rival’s flashy advertising may matter less than a quiet improvement in delivery speed.
Inside organisations, the principle helps with conflict. Not every disagreement needs a response. Some objections fade on their own, while others signal real risks. Therefore, separating noise from substance saves time and goodwill.
The idea also applies to personal habits. Our own worst impulses act like an opponent. Rather than fighting all of them at once, block the most damaging ones first. Moreover, small harmless habits can stay, which makes change feel less exhausting.
In short, Musashi teaches strategic patience. Watch carefully, decide what really matters and act precisely there. Everything else can wait, or simply be allowed to fail on its own.
In addition, this approach reduces stress. When you stop trying to control everything, you free attention for what matters. For example, a project manager who focuses on the two biggest risks, rather than twenty small ones, usually delivers better results. Therefore, selective attention is not laziness but strategy.
