I have said that my investment ability has become stronger, but that does not mean that the ability to earn super profits has increased at the same time. As age increases, awareness and experience in the market become richer, and the investment system becomes quite complete. Meanwhile, the ability to earn super profits tends to become more stable, often not as good as newcomers. Investment, doctors, lawyers are all very practical professions, at the age of 30, still very young, currently in the growth stage. When reaching 40 or 50 years old, I will also face some unfavorable situations, such as dispersal of capabilities, lack of motivation, reduced curiosity, decreased capacity, etc. In the growth stage of my investment ability, I will share all thoughts without reservation, so that others can be inspired and develop from me. In recent days, many relatives have asked about choosing a profession and career, there is a very important point, you must clearly know where the peak of your career is, at what age you reach that peak. Most professions are not strong in practical terms, they are replaceable when young. In the strongest phase of capability and creativity, you must certainly build a common professional wall, this wall can be your network of relationships, part-time work or financial accumulation, or even your father.
