Should you Feel Proud about your job compared to former classmates who are succeeding?

and your former classmates are managers, executives, this and that. Engineers, etc. while you are just an entry level clerk doing filing etc, even having gone to University. I'm totally fine with it but i feel society, my parents, and anyone else that would know me would think i'm stupid, low life, that i should be doing better. And yes, maybe i should be doing better but i don't have the personality to do other things, like i'm not good at talking, so customer service by phone and things like that is not my thing, i work better in the background.
