Suddenly realize that you are really useless? I should still congratulate you, because after all you have discovered your own problem, which means that your consciousness is much better than that of many people who think they are right but actually have nothing to do. Now that you are aware, work hard to improve yourself, both professionally and ideologically. While you are still young, make a plan for yourself and determine how you will work hard now and in the future. You should delve deeper into professional aspects and at the same time, mentally raise yourself to a higher level. Through such efforts, you will definitely be happy with your progress when you look back.
