The important thing is to learn to invest ,The rich can become richer by investing, but investment is risky. Maybe the rich will become poor the next day, and the same poor can become rich through investment, but the premise is that it must have the conditions for investment. All his money can be invested, so he takes a lot of risks. If the investment is successful, he will immediately become rich. If he fails, do you think he will have a strong mentality to deal with this? Therefore, it is still very simple for the rich to invest successfully, and failure will have no effect on the rich, but the poor have to think for a long time.
