I took up EE professionaly at around age 38. I learned really quickly, and am currently quite productive. But there is a catch. I learned the basics when I was a kid, and got into ham radio. A basic knowledge and 'feeling' for what's going on in the electromagnetic space meant 25 years later I could learn at a rapid pace.

So of course you can't go back in time and replicate that, but you can do this... Get SPICE, or better a real lab, and start messing around with the absolute basics until you can dream it like when you finally do when learning a second language.

Without that primal understanding all the advanced stuff will just be rote memory learning.

It will feel slow and you sound like someone who wants to move fast. But getting a feel for voltage and current and their basic interaction in a hands on way will set you up to absorb the more advanced stuff like a sponge.

Just because you 'know' ohms law etc doesn't mean you can 'think' in ohms law like you do when you speak your first language.

So go deep on the basics. Give it lots of boring hours. Then start getting into the more esoteric stuff.

Enjoy the trip. Its been a wonderful one for me and I hope you get the same joy
