I need a new bagpack for highschool!?

okay, well, i just started high school for the first time and i never knew how much stuff you need to carry around your classes! i am currently using an over the shoulder bag and now my back and shoulders are killing me! ive been looking online for some bags but i cant find any. if anyone can find me a cute bag that says HIGHSCHOOLER, ten points! i dont want a bag like a href="http://www.landsend.com/pp/ClassMateStudyHaulBackpack~209341_-1.html?bcc=y&action=order_more&sku_0=::LIJ&CM_MERCH=IDX_00013__0000001135&origin=index" rel="nofollow"http://www.landsend.com/pp/ClassMateStud…/a i find it really babyish. and also i was thinking if i go a black bag, how could i decorate it? oh and if it helps, im a cheerleader and have blonde hair and im tall. THANKS SO MUCH(:
