There were books about computer programming, but back then computers were expensive. We were not a rich family, so my parents were not exactly sure whether to buy this very expensive gadget. That was back in 1989.
So I learned, actually, computers were very predictable if you know how it works. You can simulate how it works on a piece of paper. I just looked at computer programming books, and wrote the program on paper, and drew a keyboard, and then simulate how the computer would respond.
After working on that for more than a few weeks, my parents were finally convinced that I’m perhaps, serious about it. It’s pretty formative, which is also why I stick with the pencil during the use of my iPad Pro here.
