why?

Kya ye why itna difficult hai.. For me may be it is..i am struggling with myself.. the biggest competitors of all of us... Ourself. I wasted almost a whole week when i know i have a very important exam next year... on which my life, trust of my family depends... But i don't know WHY i am not getting this... Again as always i am confused . Now here again i am with my confusion... Are we all confused at some point of time in our life.. Or it is just me... I know i am not perfect but it's okay let be imperfect to crack that exam.. Let's walk the beautiful road of your life with your imperfections.
