So now im ready to be great.. But i dont kno what to practice 8:00am - 9:00pm?

So i got everything but i need something or practice that can make me the best in the state or something that can put me in the NBA. Its my dream to get there but i gotta set some goals for myself. So what can i do for 14 hours even if i cant do 14 hours but what can i do so i can set myself as a leader and a amazing basketball player because i got cut 2 times same coach and now i need to be good. Good enough that i can start at V even tho im going to be Junior. Something that can help me play college bball. Something than can help me to become a amazing player in the NBA. I just dont know what to practice..
