My life.. education

Well i am meant to be revising, and instead i am typing this post. Why? Because its killing me, reading over and over again, constantly asking myself will i remember this... a few years ago i thought if i didnt do all the sciences and maths my life will be a shattered, piece of crap, a sad excuse for living, and i would have no money. Ridiculous eh, now i just can't stand the thought of all of these exams, and just picking up my biology or psychology book is like walkking into my death bed. Lol, i wonder will i do great in my A levels and become a dentist, or will i flop.. even though i would rather go and work in a magazine or do make up or something, i feel some sort of pride about hopefully becoming a graduate in a science related subject.
You wana know what my inspiration is for trying my hardest in my education.. that one day i can be looked up to and respected and be a positive role model for youth with my extensive knowledge and so that i can have a good salary and go shopping every week and buy me some indian hair weave.
Big contrast i know...
so what are the questions? Will i finnish revising for my exams or just turn mad?
What should i post next.. hmm maybe i might post a poem.
