First of all, you need to figure out what you want. If you are still young, going out to work may also be a good choice to broaden your horizons and exercise yourself. If you don't know how to learn, correct your mistakes, be diligent, don't care about temporary gains and losses, and don't be quick. It doesn't mean that you can't be a salesperson if you are introverted. It depends on your personal goals and perseverance. Personally, I feel that there is still a future in glass sales. But it also depends on what kind of sales job you are looking for. If you are interested in working in this industry, you can start as a glass salesperson in the factory in order to understand and learn product knowledge and the boss's ideas, and the requirements may be possible when you start. It is relatively small, which will be good for you to transfer to a foreign trade company or other places in the future. With your familiarity with the products and industry, it will not be difficult to find a job close to the core of the company's business or the core of your work. . You have to plan your own path in the end. You don’t give much information, so I can only give you these suggestions. You can make a five-year plan first, and then a one-year plan to see how much you can achieve by then. Good luck to you.
