man, i feel so inadequate, being a lowly cashier.

anyway, research what jobs you think are glamorous enough and find out what kind of experience you will need for them. get a summer job in whatever kind of opening position would lead you to getting that more glamorous job later. in today's economy, employers prefer people who have had college and work experience, so even if you're just working as a cashier at Walmart over the summer, it will be better than trying to apply for a higher-class job without any job experience.

as for college, most students change their majors at least once a year. i know i'd changed mine at least five times because, like you, i had no idea what i wanted to do and i was very negative about it. i wanted to be a teacher, or a librarian, or an art major, or something that expressed my talents with words and art, but i didn't get much support for it. so i gave that up and ended up dropping out. i recently came to the realization that i would be good at accounting. i wish i'd figured that out back in high school. but i'll go back someday. right now, i'm just going to continue working as a cashier until we move and i have better opportunities for both college and work. then i'll get my accounting degree while i work in a bank and i'll finally be out of the lower class.
