my future?

i feel miserable now.. i still don't know what i want now. sometimes when i think about what future i want to be, my mind will become blank. i can't see my future at all. can you tell me what should i do now? since i started studying at university, my future became more blured... i don't know the purpose i entered university. is it i really want become a manager in someday? or i really have talent in business field? i really dont know.... what i know now is i just want make me happy and free because i ady tied myself long time ago. i always forced myself to study because i don't want someday i become sales girls in shopping centre. i want prove to others that i can do it what i want. i won't let others look down on me!!! so how much i don't like to study, i also will graduate in good result. i want earn many many money.... that's only i want to do now.
by education, it's can guarantee your future....
