Secondly, we should look at our own specialties.

Finance is very extensive: money, banking, securities, futures and insurance.

Finance gives me the feeling that it is theoretical and not practical.

Securities and futures: Even if you study in school, you probably won't learn anything. Think about it: Is it useful for a group of big professors who only have theories to talk but not practice? Real trading and modeling need to be accumulated in actual combat.

Theory is dead, and actual combat is ever-changing.

The so-called: futures companies lack talents, which is the law.

Futures is a successful business for a few people.
