What should I look for before college?

I’m an incoming freshman at college next year studying math and I’m looking to do some form of internship before I start school.

Any recommendations on what would be a good experience before a SA position? I’m going to a target school so I think I should be able to do a freshman summer internship if I grind, but I am gonna be really bored this summer so I figured I should do something finance related. I’m eventually looking to do banking out of UG and then maybe quant hf.

I also live in NYC so I have that region if anyone has any suggestions. Thanks!
