What am I here for?

Why am I here on this earth? Is it to study for exams? Is it to feel stressed over Final Year Projects? Is it to stare at computer screens for the whole day? Is it to consume as much food as possible on this Earth? Is it to write blogs? Is it to get married and have babies? Is it to prepare myself for death?
Actually, thinking about it, i do not need all the fanciful, high-tech gadgets. I do not need a computer/TV/radios/camera/cars,etc. All I need in life is my loved ones, especially my dearie, and the basic means to survive. So why then am i still studying for my freaking exams tomorrow? I have no idea why.............Maybe i just do not have the strength to go "against the tide". I'm dead for my AIS paper..........
