I'm pretty good with my money... when I want to be.
I will save as much as I can when I'm looking to save as much as I can to get something I want, or when I'm getting ready to pay bills and need to take more notice of my finances. Right now, I spend all of my money on my credit card, though. I buy things with that, and pay it off with my money.
After I finish paying off my credit card for this last time, I'm not going to use it for anything other than using it to pay my phone bill and other bills my dad may need help paying. That way, I get to build credit, and I don't waste my entire paycheck to pay off my expenses. Then I'm going to save all my money, spending some strictly on food that I need to buy, for a car.
