Please help i am not sure what to do or think ?( so so sorry for the long question)

So i am a 17y.o high school student from Jordan 🇯🇴, i wake up every day trying to do my best to build my future and go into HLS(Harvard law school) but i came from a really poor region and a poor family, which is really making hard on me to build my next steps ( you know how expensive is HLS) and make me think that my dream is unattainable because i am not that genius, so how can I achieve my dream regardless the situation? Is it actually possible to achieve my goal?
