God, no. How do you decide what stack to work on? Should I use Python 2 for maximum compatibility, or Python 3 since it's the future? Should I spend my time on KDE or Gnome. Do I use Angular 2 or Angular 3? TypeScript or JavaScript? vi or emacs? Which flavor of Linux should I learn? Oh no, I chose wrong, everyone is getting $500k at a FAANG! I picked the wrong stack! I chose wrong! I lost years! I'm not getting any younger! I missed the opportunity!

Yeah, no.
