From Charlie Munger

 

First there's mathematics, like compound interest, permutations and combinations and most important probability.

 

Second, accounting, the language of practical business life.

 

Third, models from hard science and engineering.

 

Fourth, models from biology/physiology, coz all of us are programmed by our genetic makeup to be much the same.

 

Last but not least, microeconomics (pls notice he doesn't mention macroeconomics, personally I think it is more related to FX trade and also interesting). The most important concept would be advantage of scale, and do you guys know some of its disadvantages besides bureaucracy?

 

An old saying that should be posted here: "To the man with only a hammer, every problem looks like a nail."

 

What I like most is " The mind of man at one and the same time is both the glory and the shame of the universe."

 

For so many years I try to be smart, at least look like smart and it is totally insane. Reflecting on the so called worldly wisdom is a perfect way to keep one off bening overconfidence and still maintaining the passion for pursuing truth. Again for this week, for the first time in my life I understand people being the most important. Just stupid enough to overlook it.
