I figured out how to write some basic stuff, then I learned to use perf to performance tune. Being able to read a little assembly was a revolution for me.
I also chuckled about how C is non-portable; omg C++ is so much worse. In some sense, x86 asm is more portable than just about anything now, sure you can't run it on ARM, but your C++ code won't compile on ARM either and you'll be in #ifdef hell for two weeks to get it there, at which point you'll give up.
