I'm currently 15 years old student and live in the Czech Republic (central Europe). I'm interested in 3D printing, cryptocurrencies, and programming (C++). My dream is to work in an aerospace industry as an electrical engineer. In the best case in organizations like ESA, NASA or SpaceX. I know, that I should focus on science subjects in school now. Then I should go to prestige university and major in el. engineering. And then finally apply to ESA. And if I will be very lucky and somehow get a green card and some other papers, then I can work even at SpaceX or NASA. However, am I missing some important steps there? Should I focus on something or just keep going? And is there any chance, that I will meet ITAR requirements as a guy from central Europe?
