I taught myself to code from scratch. I just started writing in Basic on my Sinclair when I was in kindergarten and “got it.” I later picked up the books and courses easily without that initial study period of formal training. When I got to advanced academic materials, I already knew pretty much everything. As a matter of fact, I never learned much from teachers. I learned to read mostly on my own and followed through with most disciplines.
This isn’t a “brag” because the reason for that is a learning disability. It’s hard for me to understand teachers and communicate with them. This was a problem in my childhood but became a bigger problem when I started to teach programming in a local computer lab at 16. I was a terrible instructor. Typically we would mimic the skills of a good role model when performing a task. I didn’t have any good teachers. At least not good for my learning disability.
