Why?

Why do I do this to myself? Why do I let myself get so stressed out and frazzled over school? Why do I deprive myself of sleep in order to study more, to the point of getting sick? Why do I put so much effort into this? Why does it matter so much to me if I get a 65% or a 95%? In all honesty, is it really THAT important? No!!!

Sigh. I wonder how different my life would be if I put the same amount of time and effort and weight on other things, things that truly carry a much greater importance.
