How do I learn electronics from scratch?

Easiest way is to get an EE degree. You won't do it in under 3-5 years anyway.

/Ohm/ has resources on /diy/. Don't bother them though, just read the OP.

Learn relevant physics (definitions of charge, current, voltage, etc)
Learn linear circuit theory (ohm's law, nodal analysis, op amps, dependent sources, capacitors, inductors, RC, RL, RLC, Laplace and Fourier transforms, transfer functions)
Learn transistor physics and circuits (FET modes and operation, ideal amplifiers, small and large signal models, current mirrors, differential amplifiers, etc)
Learn power electronics (linear regulators, switching regulators, etc)
Learn to use microcontrollers and peripherals (C programming mostly once you know all the relevant circuit shit)

Go spend time in a sandbox and learn to make silicon first.

None of these guys know.
Open up electronics at home and play with them.
See if you can get that old TV to work.
Then modify it to work better.
Take stuff apart and figure it out.

Just read TOE or do this https://www.nand2tetris.org/. Shouldn't take more than 2 months. For a taste of what digital electronic is like try https://nandgame.com/ .
Otherwise build circuits in logism.
Now if you want the hardware part you are kinda fucked. Its possible but you can't make state of the art stuff.

You need to be more specific. "electronics" is way too broad. On the one hand you have the basic knowledge of how electrical circuits work with passive components (resistors, capacitors, inductors) and basic semiconductors (diodes, transistors, etc.). But things like microcontrollers, FPGA's, DSP, power electronics, PCB layout and manufacturing, chip design, advanced analog electronics, RF, etc. are all considered part of "electronics". There's very little people who have expertise in all of these fields.

What exactly do you want to accomplish?

None of these guys know.
Open up a live step down transformer used to feed your neighbourhood.
See which wires do what.
Then add new wires to see if it does anything new.
Take stuff apart and figure it out.

Blow up an electrical substation.
Release your manifesto on the internet.
The industrial revolution and its consequences have been a disaster for the human race.
Live on a farm and practice regenerative agriculture.
Set traps for federal agents.
Hide the bodies well and tell no one.

Quick mode: study for the ham exam. Check with your local group. If you are in the US, check ARRL. Teenagers pass this exam, I am sure you can too.

If you want to do real electronics then get a degree, really. After bachelor's I felt like I had a grasp on it but I didn't really know how to implement most things in the real world.
After I did a master's while at the same time working part time for an electronics startup, I felt like it "clicked" at some point and I understood how to implement most things, and had touched on mostly everything at some point.

My point is that you won't get a good overview by just doing hobby projects and learning by doing. Most online resources and communities are stuck in the past using throughhole components and implementing logic using logic gate ICs (nobody serious does this). There's a certain threshold you probably will not pass without pursuing a degree or having a job as EE. You don't want to make temperature sensors using Arduinos forever.

>Head to the nearest nuclear power plant
>pop that reactor open and stick your head deep inside, only then once witnessing the true power of nuclear-originating electricity will you understand a circuit board

Head over to the large hadron collider.
Figure out how to get that thing running.
Climb inside.
Let the particles flow right into you.
That's how you transcend regular knowledge.

Just look at every datasheet in chronologic order until you get it.
