Teaching myself BASIC on a Commodore 64 in elementary school made me a programmer and set the direction for the next 40 years. Different strokes I guess.
The same for me. I only knew how to assign variables, use for loops, if->then, and use poke command. And from this specific point I started thinking about myself as programmer event that the only thing I wrote with C64 basic was a ball moving on the screen. :)
