What's a good stay at home job I can do at 15?

So I'm 15 years old, and super smart. The only thing is that I procrastinate. I'm wanting to be tech sauvy because I'm so interested in technology. I want to go to Full Sail University for Directing and Programing. I'm wondering what a good job I can do at home is that I can get payed for. I don't exactly have a beefy computer but I'm saving up to build a pc for over $2K USD. I want to be able to record and make videos/short films, I'm a terrible artist but I'd like to be a good artist, and I don't exactly know how to start learning to program. I'm also interested in Minecraft, Sims, City Skylines. I have bought all 3 but my computer can't run them. I'm also pretty decent with autocad and can design a real house. Any suggestions?

If you're as super smart as you say so, why can't you figure out what job to do?
