Two years ago, I was working in manufacturing (mostly mechanical design). I hated my job, there wasn't any motivation or real drive to do anything worthwhile, I wasted my early 20s and felt like a total fuckup.
Decided to quit, sold my gaming PC and all my accounts, bought a thinkpad, installed Linux and started learning CLI and Python using these two books. I've always liked working with computers but I never gave myself the opportunity to fully commit to anything. Two years later I've learned a lot by myself; Networking, Sysadmining, APIs, Automation, Cybersec, etc, after working my way through helpdesk, IT and entry level programming jobs I've finally landed a really cool job as an automation engineer. You guys have no idea how happy and fulfilled i feel.
I've also learned a lot through small projects and ideas i got from this forum, and this is my small thank you to everyone, there are some really cool and ingenious people here.

It might take some time, it might break your spirit knowing how complex the world is, but never give up, there is always a way.
