Sun Tzu said: 25. These military devices, leading to victory, must not be divulged beforehand. 26. Now the general who wins a battle makes many calculations in his temple ere the battle is fought. The general who loses a battle makes but few calculations beforehand. Thus do many calculations lead to victory, and few calculations to defeat: how much more no calculation at all! It is by attention to this point that I can foresee who is likely to win or lose.
In business: 25. These business tools, leading to success, must not be made known to the competition in advance. 26. Now the business leader who succeeds makes many preparations in his office before key actions. The business leader who fails but makes few preparations beforehand. Thus does much preparation lead to success, and little preparation to failure: how much more no preparation at all! It is by attention to this point that I can foresee who is likely to succeed or fail.
