Sun Tzu said: 26. In night-fighting, then, make much use of signal-fires and drums, and in fighting by day, of flags and banners, as a means of influencing the ears and eyes of your army. 27. A whole army may be robbed of its spirit; a commander-in-chief may be robbed of his presence of mind.
In business: 26. Use the relevant means of communication and navigation to strengthen the effectiveness of your actions. 27. A whole company may be robbed of its spirit; a CEO may be robbed of his presence of mind.
