I wouldn't change anything I did in my adolescence.
Late fifties and early sixties were "changing times." ....In lower school, the teachers that inspired me the most were the ones that encouraged that spark of sheer desire to solve difficult problems....It wasn't but a few days into the (Computer Science) class before I realized this was the subject for me. It was so fun, I forgot the time of day. I spent hours and hours hanging around the computer labs working on those first programs.
