What should I do with $110,000 as a newly 18 year old?

Invest in fixed annunities. Any bank can set it up for you. It might only pay 3% but you can't lose a dime. It's usually set up for 7 years

college. and invest anything left over

First, I would take out $5500 (5%) to spend on whatever I want. It will be easier to be responsible with the rest if you indulge yourself a little.

Then if I had some career interest, I would use it for college or trade school. If any was left over, I would invest it in a mutual fund.
