Truth is, if you're broke you don't have the means to pursue your dreams, unless your dream is to sit under the overpass with a cardboard sign and a bag of butts you collected off the parking lot. If you have a job you just might be even worse off, having a roof over you while you sleep, but not much, not even time.
You could get arrested. Then you'd have a roof over your head and plenty of time to pump iron and read books about accounting and shit.
So, find some way to get enough green to buy some dope and booze ( stealing it works best) and don't worry about any of that "getting a head" crap they pump you full of in school.
