The forums are extremely useful because you can submit your work for feedback and they'd point out things you didn't even knew were a thing. For example, suppose you're designing a PCB for your project. You can design your PCB, submit it and ask for feedback. You'll then have a list of things that are wrong in your board. Rinse, repeat. On something like the third board iteration or fourth, you would have a board that is pretty darn good for a beginner because it went under the eyes of really good people. You wouldn't get there on your own on the third iteration and your board would still suck. Your skills will take off pretty fast.
Forums are also good because you can see what people you interact with on a regular basis are working on, their projects as they're building them, etc.
Analog:
There was a good site that had a recommendation for learning analog electronics. It has changed but here's a link to a previous version:

- https://web.archive.org/web/20160225152142/http://www.wisewa...
The site offers recommendation and a "track" as a function of your experience and what you want to do. It also offered review of the materials recommended (application notes, books, etc).
On PCB design:
PCB Design Tutorial, Dave Jones (eevblog): 25 pages of excellent actionable information to make your boards professional looking (routing, tracks, pads, etc.):

Also from Dave Jones, check out his soldering tutorial if you want to solder:

On entertaining and informative content:
Dave Jones channel in general is good to acquire culture. He also has in mind that you might not be wanting to spend thousands of dollars and gives you good quality/price ratio tools.
Ben Krasnow's "Applied Science" channel. This one is amazing. https://www.youtube.com/channel/UCivA7_KLKWo43tFcCkFvydw. Ben is concise and I like that a lot. He does not ramble. Technical talking.
Books:
For books, there's a big book by Tony Kuphaldt titled "Lessons in Electric Circuits", available on his website (https://www.ibiblio.org/kuphaldt/electricCircuits/) but also on the AllAboutCircuits forums.
Tony Kuphaldt is prolific and has another (3000+ page) book titled "Lessons in Industrial Instrumentation", if you are interested in control and instrumentation, feedback systems, etc:

There's also "The Art of Electronics" to learn stuff every time you pick it up.
