Since I was a child, there have been countless teachers and parents around me strongly opposing the idea of relying on interests to make money. But this is a simplistic suggestion. It's not that people can't make money from their interests; rather, you need to find a productive interest, not a consumptive one. For example, "eating" is consumptive; it only costs money and doesn't generate income. However, if you can provide effective reviews after eating, that becomes productive, and you have the opportunity to become a food blogger, which can earn you money. But this also imposes additional requirements on a person, because a profitable business will likely require you to do more than just one thing well. In addition to having a good taste for food, you may need to edit videos, take on advertisements, connect with advertisers, learn how to make videos, and understand the platform's algorithms... We call these "skills." So, making money from interests = having a productive interest x skills that match that interest. For me, my interest is to clarify things that are unclear in the business field, and I am willing to write, edit videos, and build communities for this purpose... So my interest can be converted into currency. A more complex aspect is how to build "skills that match my interests"; this itself is also a business problem, and it is also my interest. So, my interest is my interest, and how to make money from my interest is also my interest. In the programming field, there is a concept called bootstrap, which originally means: pulling oneself up by one's own bootstraps. This seemingly impossible action can be realized in a system: the system uses its own output as input to achieve self-starting and enhancement. This is a growth model with zero external dependencies: I can use my current self to launch my future self.
