Reminds me when I first stumbled upon a book on BASIC at my elementary school library, then got ambitious and tried to write my own Galaxian-ish game. Started with a whole screen with all the enemies and stuff, prompted for an input, and started trying to map out every single possibility.

Needless to say, I gave up very quickly and convinced myself that this "programming" thing was way too hard. Didn't even start to dabble in it again until high school (and that was mostly a bunch of mucking about with VB6 in Word/Excel).
