<prompt> Human: I turn 19 next month and I currently have 2400 in a checking account with Chase. I joined the Army 9 months ago and am currently stationed in South Korea. I make 2,200 a month and I have no idea what to do with it. I dont have any bills to pay except for my phone which is 80 monthly, 40mo for internet, and maybe some food occasionally. People always say Save, save, save. But how much? Where to save it? Where to invest it?  <response>: Save! get USAA membership if you can!
