Probably pay down my credit card. I could have it paid off in like a paycheck and a half (1.5 weeks) but I'm not too good with my money ha.
Its not tough so long as you aren't spending much with them. It took me about 2 months to get mine paid off after I got my new job, but that's because I'm constantly using it for work. Now, if its something not work related I use it for, I pay it off immediately.
Just set up a budget if you can't pay it all off in one shot. I had trouble managing money until I started using spreadsheets for it. I feel like having it visualized on paper makes it a lot easier to deal with. Instead of comparing your debt to your bank account.
