I never studied CS. This was probably around 2004 (I was 10), I just got my first own computer. I used to mess around with HTML and JS previously, like making obnoxious marquees and so forth, but then I met this guy on DC++ who taught me the basics of VB. Before that I'd always thought of people who could make compiled exes as magicians, and I suddenly became one of them. It was a very empowering moment. While others were playing, I coded apps such as a geometry calculator for school, a TCP chat program (not as cool as Zuckerberg's), and so on.
