  For the longest time I didn't have internet consistently, so I 
often had to figure these things out solo and alone. Honestly I'm 
still new to figuring out where things are on the internet, or 
what I need and don't need.

  Doesn't help being self taught means I don't know some of the 
lingo. What is map? What does reduce do? What's a HashMap? These 
things by themselves (to someone relatively new) doesn't make 
sense, and the STL and C++ seem to actively push me away from 
understanding it so I dropped them wholesale. The only libraries 
that made sense and I would rely on were the bare minimum core 
library ones included in the '88 CPL including bare minimum 
string and IO functions.

  Perhaps that's why I'm still shy about learning some of the 
libraries and understanding some of the more ingenious solutions 
that can be written in a couple lines rather than building my own 
solution which is clunky (but better than C++).

  Although I'm doing better than I used to, it's still a chore. :(
