Grades

The reason why I panic most of the time is all due to grades. Many people tell me your grades does not define you as a person. But can someone please explain to me why my grades determine if I fail or not? Failing and succeeding in life is what define you as a person in the future right? So how does this add up then?

I know I am not making sense at all, but this is Otao Knews for today and until next time.
