Saving Money For College

I am 16 years old trying to pay off my vehicle, pay my cellphone bill/ buy a new one because my old one quit working and most importantly save for university. I work every weekend when I don't have school or extracurricular activities and as many hours I can get in the summer. It's hard to pay for all of these and for gas money to get to the places I need to go and still save money for my future career plans to go to university to be a Veterniarian. My parents are not nesscarliy poor people but there are not rich.... I find myself trying to save money but noticing it all being payed back towards a vehicle, cellphone, hanging out with friends, & sports. I'm trying my hardest I can at school, work, sports, and trying to mantain a social life..... Add having to try and save for university and it's near impossible. I know there's so many important causes you could put your money to but if I can't at least pay my rent in college I have no idea what I will do. Please donate, I know I sound like a typical teenager but I promise I'm trying my best. EVERY PENNY COUNTS, when your a broke teen saving for the future!
