<prompt> Human: Hi rpersonalfinance,Im a 20 year old male living in Boston who will be making 29 per hour until December. This will be my first real corporate job, worked at a a casual start up last summer making 23hour.Currently, I have about 500 in my checking account. I dont own a credit card. I live with my family so no rent expense. Only expenses would be occasionally eating out 160 per month, haircuts 30 per month, and the train 100 per month. I still need to buy work clothes, which will likely come out to 250. Im not sure exactly how much student debt I have, and will update this post once Im back from vacation in a few hours. But off the top of my head, roughly 20k by the time I graduate. What do you recommend I do with my money? Im open to investing from ETFs to option trading lol. I also would like to open a credit card DiscoverIT?. Any advice is appreciated!  <response>: Same advice I gave my brother working the same type job...If you are carrying subsidized loans put the 30k in a high yielding savings account and not in the market since the time horizon is low on this cash. If you are not carrying subsidized loans then pay those loan off right away. Once you graduate use the money to pay off student loans . He worked two summers at the bulge bracket firm and was effectively able to pay off student loans with the cash
