Yes – Because good grades might help you progress in life.
No – Because it clouds you, it gives you a false sense of achievement which might not be true.
Graduation is just the beginning of life, it’s just the first step, and you need to learn a lot. So the best thing to learn is “How to learn” anything, anywhere, how to keep un-learning and learning.
Life’s battle is mostly won by someone who is ready to change, ready to adapt, ready to learn, and that too at a fast pace.
So enjoy your graduation but don’t get too comfortable, life is coming and you better embrace it with your attitude rather than your grades.
