Man you need to save you're money. I try to save as much as I can even though I have to pay gas (which is 100 a week), insurance, any extra groceries, books for school, etc and I am still in high school!! I've been able to save a little bit here and there for bait making with my minimum wage summer job because I havn't bought anything i didn't need but once I spend the extra $$$ I have, I'm not buying anything for a long time.
Luckily, when school starts back, my parents will again be flippin the bill for food, gas, clothing and all the necessities haha but until then I'm on my own.
Like I said before though, save your money for when really needed it because once you spend it, that money is gone.
