JSYK, I started programming on an Apple II--with no formal CS training
It wasn't until I left the Air Force (where I worked on F-15 computer systems) that I went back to school and got that formal training. My instructors hated me because I usually had a functional program ready before I even had the algorithm written up.
I'm not a coder today more because I don't want to be, though I admit there are a lot of apps I wish were available.
