I'm an old man and I like learning the "watch a video" way. I pay for Udemy courses when they go on sale which can range from $12 - $20 bucks. You code along with them at your own pace. I grind out lessons like JRPG grinding for EXP. If you don't want to spend money then YouTube has a bunch of free courses.
When you get good enough with a language you supervise the A.I. to do the copy paste work.
If you're into game development pick up C# or C++. You'll be able to make basically any type of game you want and have a high demand skill for businesses. It may not be your passion but it can pay the bills from home.
I see you're messing with Linux gaming. Linux is used a lot in servers and cloud services.That's always in demand.
Edit: There's also online courses that gamify learning. Not my thing, but it may scratch the instant gratification itch.
