The real question is, given all the materials on the internet that can literally tell you why these tools are useful (I mean, surely if you just read the docs you'd find out?!), why have you not done the work?
It feels like you're in your comfort zone and rationalising why you shouldn't do the work. I mean, is finding a job and being employed not motivation enough?
Perhaps look inside yourself and be honest first. It sounds like instead of admitting that you need to do some work and learn some things you'd rather blame outside circumstances for your lack of personal progress.
I don't mean to sound harsh - sometimes we just need a reality check!
Take responsibility, get out there and DO THE WORK. A new world is waiting for you just over the hill.
