exams again soon

CNY 07 is over, and coming up is more studies and assignments. Lots of stuff to study, understand and remember. Lots of people around me seem depressed and stressed. Some even fall sick to the extent of vomitting and having diarrhoea. As for me, i do try to revise but i cant seem to get myself to concentrate properly. My mind wanders off and i always end up doing something else instead. I know this isn't right, i'm all grown up and somehow independent already...I should not behave like this. I should have self-motivation, control and discipline over myself....*sigh*.....sometimes, i ask myself "why am i like this? why cant i be like other people...they are studying so hard..." i'm hopeless.....=(
