dont listen to people that tell you to ditch it and pay for a cell phone or utilities instead. having a credit card is perfectly fine. just control yourself. i have 3 credit cards and i just turned 20, but i dont have any debt. its not a hard concept.
get a credit card through a gas station first of all. anyone that doesnt do this is simply a moron. an utter, complete moron. you have to buy gas anyway, and if you put it on a gas card from that gas station, you get free gas every month. i simply cant understand why anyone wouldnt do this.
and who the crap gives a college kid a $3000 limit? it all depends how you work it. im a college student and my limit is $11,500. its a rewards card, so i buy everything on it and pay it off every month...and at the end of the year, i get a ton of free stuff for buying what i would have bought anyway. it is the only thing that i can honestly say is free. carrying a balance to earn credit is wrong. it makes no difference. buy stuff, and then pay it off. treat it like a check card and you are good to go.
