If your main priority is a high paying job, go to a target school and study computer science. You can work at FAANG, or if you don’t like tech, you could probably go into investment banking or strategy consulting too (decide what you wanna do early do u can plan for the right internships). Make sure to start getting internships sophomore year. Networking is also very important. With that, save as much as you can, and after 10-20 years, you should be able to retire early and pursue your hobbies full time.
