Wow! This is how I learned to code too! I remember when I around 12-13, I wanted to figure out how to make my own message box in Windows (yes, I was weird). But I didn't know there was such a thing as "programming". In fact, I had no idea how software was made.

Eventually I stumbled upon Game Maker -- I think it was at version 4 when I found it. So I began creating little games with that cheeseburger icon and snowmen. Eventually, I realized that this thing called GML would let me do more. When I looked in the help file, one of the functions said to enter an "argument" and I seriously spent like 2 days trying to figure out what an argument was.

Eventually I got a Mandelbrot fractal going in Game Maker and discovered C at that point.
