My friends laughed at my stupidity and simplicity. What should I do?

I think you think it's useless for you to say so. As you said just now, the living expenses are more than the salary, so you take the living expenses from home if you want to think you are useful.

I don't think people who just came out should mind how high the salary is (you have done this very well). The most important thing is to accumulate experience in society and learn a skill.

Of course, people who have just come out have to stand the test of society, and it is inevitable that some people will be dissatisfied with you and make things difficult for you everywhere. At this time, you must learn to be patient. Suffering is a blessing. When we go through all kinds of difficulties, we will be mature and the road ahead will be easy.
