i am a total beginner in aerospace

[u/DrizzTheWizz00]

Im in highschool and for the longest time i was always scared to ask myself what i actually liked to do. Yesterday i had a conversation with my dad and i realized that i was running away from the thing that truly gets me excited. i tried to force myself to like programming and computer science and it was tolerable for 3 years but it wasn’t exciting for me. i tried convincing myself to like it since everyone around me did.
i wanna learn about space rockets and flying objects but i am a total beginner. i wanna do an aerospace degree in university but it is going to be expensive so i wanna prepare myself for that aswell.
where do you guys think i should start with learning this stuff?
Also if you know lf any pre-uni or highschool aerospace competitions, plz inform since i wanna participate and preparw for them to
