What should I start learning if I'm going to work with computers when I get older?

Hi, I'm only 13, but I really like computers and know quite a bit about them. I'm kind of young and have a long ways to go until college but I want to start early and gain as much knowledge as I can to be REALLY GOOD at my job. And I figured that I wanted to work with computers. As for what kind of job with computers (technician, engineer, scientist, programmer), I don't know. So I've heard of learning to read Java, C+, and C++; but that seems a little too much right now! So I was wondering, what should I start learning to get a head start? I already know the basics of computers and everything like that, and a little more. So any advice/help would be great! Thanks!
