Don't care too much about age. If you graduate two or three years older than other students, you also have your own advantages, that is to say, you have more social experience and experience than them, so that you will enter the state earlier than them when you work. A friend of mine is 30 years old and is still preparing for a master's degree. After graduation, he will be in his thirties before he begins to enter the society. Compared with him, your age has become an advantage. Brother, we are still young, there are still many things waiting for us to do and a lot of knowledge waiting for us to understand. Don't dwell too much on this problem, just do it if you have an idea. I hope you can get out of your little shadow and take a long-term view. Finally, I wish you all the best.
