To kill time, drive something that interests you.
If you want to spend your whole life and earn a little money, you should open what you are interested in, because what you are interested in will be invested with your heart.
There are many small projects at present, but be cautious about some so-called franchise stores.
Many petty bourgeoisie projects set up shop first to see if they can make steamed bread, cakes and clothes. They can't do anything, so they sell other people's things, such as opening children's clothing stores, renting counters in shopping malls and selling accessories. No matter what dock they make, the most important thing is to open a duck neck.
It doesn't matter what you do. It is often said that all roads lead to all walks of life in Rome, some do good things and some do bad things, and even the best industries have closed down.
After opening, you should devote yourself to sowing first and then harvesting.
