I think every successful learner in CS or programming is doing a large amount of experimenting. Many books I've read encouraged or even required the reader to extend the software or algorithms written by the authors.
Growing in a poor Eastern European country with a cheap Z80 computer, meant experimenting was needed for me to learn as a kid. There were only a handful books about Z80 programming and all were about Basic and also very basic. The other books were either in abstract CS territory, full of high level math or about some big iron machines and languages that did not run on my Z80.
So after reading somewhere that I can poke some address to obtain a particular effect, without explaining why, the next question was what happens if I poke another address?
