Speed in strategy (Speed and Surprise)
Decisive action beats elaborate plans.
Speed in strategy is a recurring theme in The Art of War. Sun Tzu warned that prolonged campaigns exhaust treasuries, tire soldiers and invite other rivals to take advantage. In his view, no state had ever gained from a long war, so the goal was a quick, decisive result rather than an extended struggle.
The logic is about cost and momentum. Every extra week of conflict or indecision burns resources, attention and goodwill. A fast move also limits the time your opponent has to understand what you are doing and to prepare a response. Speed concentrates your strength into a short window, while delay spreads it thin until little remains.
The mistake is treating speed as permission to be reckless. Sun Tzu paired swift action with careful planning beforehand. The army that moves quickly does so because the roads, supplies and plans were sorted out in advance. Rushing in unprepared is precisely what he cautioned against. Prepare slowly, then act quickly once the decision is made.
This connects with deception and the indirect approach, since a rapid move is far more effective when it also comes from an unexpected direction.
Example
A couple has argued for months about whether to repaint the living room, collecting dozens of colour cards. One Saturday they agree on a firm rule: pick from the three favourites by noon and start painting after lunch. The room is finished by Sunday evening, and the endless debate that was draining both of them simply ends.
Try it this week
Pick one decision you have been circling for weeks, set a short deadline, and commit to acting on whatever you choose.
From Art of War, Core Nine (Sun Tzu · 500 BC).
