<prompt> Human: Im quite fearful of what to do with this money. My sister spent all of it the same amount over the course of 7 months. Im living with my father now. He is willing to pay for my 4 year college tuition so Ill be relatively debt free. So since thats the only major expense i see in the coming years and since its paid for Id like to know what to do now.P.S. my dad is nice and all but hes a really bad spender too so im not comfortable asking for his help  <response>: 6 months of living expenses in Ally or equivalent savings for emergency fund. 20k should more than suffice. Do not touch this except in extreme emergencies. Payoff all outstanding debt you have, no matter how small. Invest the remaining entire lump sum into a Vanguard or equivalent low expense ratio index fund. If you dont know what this means, there are tons of people here who can help you figure it out. Do not tell ANYONE about these accounts. Live your next 20-30 years of your life as if this money does not exist. Work hard in college, get a good job, max out your 401k in that job, live frugally, invest. Dont tell anyone about these accounts.
