<prompt> Human: Long story short, I contract for two different departments of the same large company, and their accountants fucked up big time. It took me ages to realize it, but I was getting 3 paychecks every time I should have been getting 4. They were extremely helpful and apologetic about the mistake, and lumped me the back pay. Now I have 14000 more than I did two months ago. This is enough to pay off most of my remaining student loans, or I could just up the amount Im paying each month. I also have the option to just sink a solid 5k into my IRA. Or buy a motorcycle. Whats the best move here?  <response>: Always buy a motorcycle it its an option hehe. But not a new one, just a nice used one and still pay off your student debt.
