Advice for someone turning 18

I’m turning 18 this month and i’m going to have so many more opportunities opened up for me to make some money.

I have a few thousand saved up, $2K+ in cash and $4K in my bank account set aside to save. Aprox. income of $500 a month from working.

I plan on opening up a BOFA credit card as i’ll be approved easier as i had an account since I was 14, no problems.

Possibly opening up a trading account to put some savings into an index fund.

Besides that i plan on finding some new hustles which i’ll deposit into a chase bank account i’ll open up. I’ve been looking into buying/renting a car on turo, whatever would make me some sort of income.

I’m going to have to be spending 30K a year for the next 4 or 5 (if I go for a masters) with a scholarship at a city school for a business degree (MIS).

The idea of going into debt is really something i want to tackle and i haven’t even committed to the school yet.

All advice would be helpful, thanks!
