In fact, why do you habitually use the word "undergraduate"? Because this is your only feature. If you deny this, you are really a mortal.
As for your dissatisfaction, there are actually many reasons, but in the final analysis, it is still a problem of the times. Your situation is not a special case. Many people are just like you.
Don't complain If you still have ambitions, think about it. God won't close one door, but he will open another. Not as pessimistic as you think. But don't be too optimistic. Being too optimistic means not biting off more than one can chew. Man is a hairless monkey at best.
Think about those who have awesome titles, which may be your goal, but they are all deified liars. There are many people like Liu Yingxia and Shi Yuzhu in China.
