Only by doing what you are good at can you go further. You can make a concrete analysis according to your actual situation. If you are a food blogger, the most basic thing is to be able to cook and understand the knowledge of cooking ingredients. This aspect will also involve the purchase of ingredients, and it still needs certain economic conditions. If you are a learning blogger, you need to know enough about learning resources and be able to sum up your own set of learning ideas. In this respect, there should also be an exact field subdivision, such as according to professional fields, design, engineering and so on. In general, we should consider our own interests, economic conditions and our own abilities to make a positioning.

There is no best, what suits you best is the most important. I hope the landlord can do something!
