Do you think most people suffer in life later on because they were not good in study

I am not sure, but sometimes I feel most people who complain why there lives turned out to be ordinary or pathetic after 30's is because they were not good at studies…then you don't get good degrees, no one wants to give you a nice job…everything about you looks ordinary or pathetic to the point you start questioning yourself…and that answer is maybe coz you were simply not good at studies meanwhile you were at it and there is no going back….
