Perhaps most people, as newcomers to the workplace, are afraid and confused, but to overcome this emotion, because they are afraid of being useless and have a normal heart, they must strive to improve themselves. I believe it won't be bad anywhere.
You can give yourself positive psychological hints and tell yourself that you can. At the same time, we should gradually get rid of the naive psychological state, and don't look at society and the workplace from the perspective of a college student. Because the workplace is very different from the school, we are well protected at school, but when it comes to society, we have to rely on ourselves.
We should accept the injustice and viciousness of society, realize our own shortcomings and learn from the excellent people around us. I believe everyone will make progress.
Finally, this is a very important change in your life. I hope you can take it seriously and don't be nervous. When you roam the earth, relax and show all your strength.
