Sorry to hear about the passing of your grandfather. It sounds like he was a good guy and just wanted you to succeed.

Unfortunately, $1000 isn't a lot. If you have debt, please take care of that first. If "the standard" is 8-10% per year in the market and your Credit Card interest rate is at +17% it'd be smarter and more cost-effective to pay that off first.

Or full port $BOIL and pray. Either or.
