I want to say that what you have learned will never be out of date. Unless you can't use it, what you have learned before is really useless. I am a real example myself. My major in college is business English, but I haven't been engaged in professional-related work since graduation. We are junior college students. Although this language major has high requirements in all aspects, it is still difficult to engage in high-end industries. After all, English majors in undergraduate colleges are very popular. People have always had an TEM-8 certificate for English majors, but we only have CET-4 and CET-6.
And what you learn is to see if it can be used, not to say that this knowledge is useless. We have learned more knowledge, enriched our brains, and greatly changed our way of thinking, which will also be of great help to our communication with people. Therefore, you should know how to arm your mind with this knowledge. Mastering one more skill or skill will also give you extra points when you are looking for a job or doing other things, which will definitely come in handy. It is what we often say, "Multi-skills don't weigh you down."
Finally, going to college is the dream of many people. Even if it is not our favorite major, that time in college is the best, most comfortable and most comfortable time in our life. Although there may be regrets, misses and shortcomings, it is still beautiful. After all, it was only once.
