This question already has an answer here:
I just turned 18. I have a bank checking account and I'm thinking of starting a Roth IRA with some of the money I am earning this summer. I have a credit card linked to my parents account (I use this to make small purchases here and there) which is think is showing up on my credit history (I use credit karma to check). I have no real steady job (just some hourly work here and there) and am going to college in the fall (luckily my parents will pay for my college tuition). Is there something else I should be doing and is opening a Roth IRA a good idea?
Note I'm pretty inexperienced with financial matters (being a young adult) but I do have time to research.
