Sun Tzu said:
Know [the] other, know [the] self, hundred battles without danger; not knowing [the] other but know [the] self, one win one loss; not knowing [the] other, not knowing [the] self, every battle must [be] lost.
The obvious that everyone knows is know the enemy and know yourself, hundred battles fought hundred wins. But what is less obvious is this
Not knowing the enemy but know yourself, the winning rate is only 50%. In his words, One Win One loss.
Translating this into practical investing. We must know what kind of investors out there just like knowing major martial arts out there. What are the strengths and weaknesses of each school? I like what Bruce Lee said you have to balance between instinct and control. Too much of control then you are too scientific then you are turning yourself into a mechanical man. If you push yourself to the other extreme on instinct then you are just too unscientific.
We ought to know that each type of investing school has its own strengths and weaknesses.
