If you want to work hard, then study hard to earn a hot major, and you will work better in the future.
If you think there is little hope of learning, then you can pursue your hobby now. Don't plan how long you will work in an industry. The catering service industry is a youthful meal, but it is also the best way to hone a person. So don't think about how long you will work in coffee, wine mixing and West Point, just accumulate experience. After working for a few years, your mind will change and you won't want to go to work like this.
You'd better narrow down your choices. One is that you go to school and find a good job to go to work. Second, you learn social experience and go into business.
You can also study these in your spare time now, so that you can study during the holidays.
If you learn to make coffee, remember to learn more about it later. I used to work in a coffee restaurant, and now I am also engaged in the coffee industry.
