You can choose one of the four things: cake, bread, toast and sandwich, and become your own skill. However, the following aspects need to be considered:

First, be clear about what you like. If you don't like it, it will be difficult to stick to it and you will give up halfway. One of my relatives, that is, my family, chose to help him learn auto repair. As a result, he simply couldn't accept such a working environment. It's important to choose what you like.

Second, plan how to develop in the future after studying. Go to work or start your own business? If there are geographical restrictions on starting a business, what kind of stores are suitable for opening in the future and what to learn? This is more efficient.
