If a person wants to cross classes, he may need to break through these steps. The original family, the original environment, break through the language restrictions, break through the national borders, and break through your subconscious. One is the original family, many people are greatly affected by their parents' cognition, if this cognition itself has greater limitations, it will become an invisible shackle in your growth process. The second is the native environment, I grew up in a third-tier city, and I am deeply touched by the lack of resources in small places. This sense of deprivation is actually more likely to motivate the evil of human nature. First-tier cities have preliminarily screened people through urban dividends, and it is easier for you to make high-quality friends. The third is language restrictions, you have to break through national boundaries and go out to see what other people's cultures are like, so that you can make comparisons, and you will not only be superstitious about one voice, so that you can look at many things from a global perspective and find many arbitrage opportunities. For example, in the currency circle, there are many overseas friends who continue to carry out geographical and language arbitrage based on their understanding of different countries and language advantages, and this information gap will always exist. The fourth is to break through the subconscious, no matter what stage you are in, the most important thing is to fully understand yourself, which is also a lifelong topic. Many times I think I am making rational choices, but in fact, I am subconsciously driven and decided. If you really want to break through, you must first be constantly aware of yourself, and then recognize your subconscious bug, and gradually fix it.
