I really want to go to work and become a useful person inside, but I will never get there.

You think too much. What do you mean by useful people? How many people are really useful? Forget it, go to work if you want, and don't expect you to find a suitable job in the early stage. And the working environment. Because you are not familiar with interpersonal relationships and other things in the social environment. You can adapt to two or three difficult jobs first. I'm sure something will go wrong at first. But after each time, you should sum up and accumulate experience slowly to find a good job.

Work is too easy. It's just that your work makes a profit for the boss, and I'll give you a little. Start studying more, talking less and being generous. Say nice things about others if you want to talk. If someone bullies you, you can fight back. Fighting back is not about hitting people and swearing. Say something to let the other person know that I am not satisfied with you. Finally, don't mess with me

Don't lose heart after several failures. Summarize it and you will get used to it.
