<prompt> Human: tl;dr What do I do with 450USD that I get per month other then letting it sit in a savings account?Hi, my birthday is in December, when Ill turn 18. Am I right to believe that being under 18 will limit tons of options for me?Ive been getting 800USD pretty much every month for a while now. My current monthly expenses is 200USD for food, and other personal things. Ive saved up 2,000USD in my savings account. I dont want to buy anything. I dont need to buy anything. I pretty much have everything I want right now. I budget 350 every month for my food, subscriptions, web hosting etc.I graduate high school in June 2014, but I wont be attending college until September 2016 at the EARLIEST. During the 2 years, ill be in the military, I dont think ill be having much time for fun. So by the time Im ready for college, I will have at least 19,200 saved up. Is there anything I can do with the money, so that I will have more when I start college? Other info that might be useful. I get a .30 rebate every month, if my balance does not fall below 1,000. If it does, I get penalised 2. I can answer some questions if need be. Thanks in advance for the help :  <response>: You said the military service is compulsory. Korea? Israel? You are getting a lot of US-specific advice so it would probably be better to say where you are.
