This is obviously a unavoidable problem for straight-A strikers like me. My mates believe that I am nuts, and that I only concentrate on my study, and that my life is no fun. What's wrong with achieving high scores anyway?
Nothing wrong with high marks at all.....just remember that all work and no play makes jack a dull boy.....it sounds like your still young maybe at Uni so go and enjoy yourself as well...you can do both.
If you're happy doing what you do, then don't worry what others think, though it is a shame if you're studying to the exclusion of everything else. Then again, if you have to study that hard, perhaps you're not as clever as you think!
