I think you have a heart of comparison and vanity. It is normal to have these psychology, but it is wrong to pay too much attention to this aspect.

as a graduate student, you still have this comparison mentality, which I think is very abnormal. Everyone and every family are different, and their economic ability is different, so simply speaking, you can live as much as you have in your pocket. Moreover, I have a postgraduate degree, so I should have a clearer self-awareness and self-knowledge.

I believe that as long as I work hard, I can realize my desired life experience one day.
