How do I get into an Ivy League university

I’m a freshman in hs (I know I still have time ) and I wanna get into my dream uni . I only have 1 special class (honors English ) I live in a small school town (transferring to a charter school ,2nd best in my state for academics next year ) I wanna do double major (maybe stem +poli sci or economics + poli sci ) I’m very interested in feminism and womens liberation/struggles . I feel like I won’t get in , I know I have time , but I see a lot of qualified ppl not getting into their dream schools and it dosnet give me hope in some ways :( .

To add I also have all As and 2 Bs currently .

Advice would be nice or some good hope stories would be nice as well :)
