What can be done to correct money?

It is important to know that not all industries earn the same amount of money. As for what kind of industry makes the most money, I only have one understanding. Any industry makes money, as long as you are the first in the industry! It may be difficult to say this, but how can we make money more easily? People who make a lot of money are successful, so if we want to make a lot of money, we have to learn from successful people, copy and imitate their behavior and thinking mode, so as to "succeed at speeding". Why can successful people succeed? That's because successful people are not what we think and see, so they can succeed. Ok, then tell me what kind of industry you care about is the most profitable. Personally, I think it is better to study and grasp what kind of industries and products will make the most money in the future than to grasp the information of the current market and what kind of industries will make the most money at present. Because maybe an industry or a product doesn't have a big market and a big demand at present, but there will be a big development and a big market in the future, so that we can make a lot of money and make money more easily. Because we have seen the future development trend, mastered the future market, made future money from now on, and reduced the threat posed by future competitors. So we're the only ones eating cake? Not many people come to dinner!
