And everyone makes mistakes, but remember, you should learn from some mistakes and don't make them again next time. No matter this company or you leave for the next company, you always make the previous mistakes, so you can't stay anywhere. Then, if there is anything you don't understand in your work, you can ask your accommodating colleagues and ask them for advice. Be modest. This can avoid many problems. In short, come on, everything is difficult before it is easy. Don't be afraid to make mistakes. Be careful, don't know how to ask. It's gonna be okay.
