At some point I heard about C and got "The C programming Language" and started to learn that. I've used that for more projects in the ensuing 30+ years than anything else. Along the way I also learned/used Java, C++, and I'm now learning Go. I've scripted with sh/bash, Rexx, Perl, Python. I've dabbled with a few others like Rust, TCP, PHP and probably others I've forgotten.
