I am also studying, graduated from foreign language major, and majored in engineering. Can you imagine? It's not that it's hard to find a job, but whether you can integrate what you have learned and seen and apply the so-called theory to practice. This is an old topic, but I'm afraid few people can do it. Why do you all ask for biographies of successful people? Do we only see the endless scenery along the way? Did you see anything substantial or regular?
Off topic, it seems, hehe
Or feel that you are working hard, say more.
To answer your question, you can stick to the above. If economic conditions permit, choose part-time sales and continue your studies. Remember, it is for sale! Recommend a video for you to see. I don't know if you have seen it. This is the "secret" I used to train employees when I led a team in Shenzhen. Go to Baidu to search, feel and listen.
If possible, I hope to communicate more. Maybe it will help you a little.
Good luck!
