I learned electronics before computers (my father was an electronics engineer at the time) and I was more or less taught Turing (intuitively) on a hardware level. So the idea that anything is possible and their is no such thing as magic when it comes to computers (modern ones included) made me keep trying because I knew it had to be possible on the gate level so it was just a matter of trying. When I still had an Msx, my friends where getting Amigas with much better capabilities. I knew that, basically, my computer could do the same: by that time I was well aware of math and algorithms, so I was able to code up ‘real 3d’ but it was so slow that my poor system had to stand there all night to calculate a rotating cube and put it into screen 5 buffers. Now that is all silly stuff, however, it did make me remember my whole carreer that there is no magic. Something which some people who learn high level only, do not seem to have. They actually seem to believe that the provided abstraction (by libraries or language) is the limit to working the machine.
