The core of "Sun Tzu's Art of War" consists of three sentences:
The art of war is first not a method of fighting, but a method of not fighting;
Not the way to victory, but the way to invincibility;
It is not a method of fighting and winning, but a method of winning first and then fighting.
The common saying is that you will fight only when you can guarantee that you have a high probability of winning, otherwise you will not fight.
This is the same as how we invest and trade.
