How Do You Learn?

The best thing to do for me was listening experiments with simple materials...

Articles and books gives ideas not the low cost solutions at all...

 They sell something with the new idea....then keep the idea and dont buy any stuff...

experiment and listen....

It was my gratifying solution....

An indication that you have found a comfort level.

I became better at listening and understanding the lingo.

You made an effort and have shown an interest! Now dig in ...
The tech side (lingo) of is about the ' nature of the beast '.
Any technical background especially basic electronics / sound engineering will help move ahead quicker.
As stated this is a beginning point.

"How do you learn?" is one fascinating topic. I’ve read that learning involves making new connections between neurons, literally re-wiring the brain, which is why repetition is so often involved. But I don’t think that is what the OP had in mind. Even though it is literally the title. Kind of like the "What there is" thread. Both truly fascinating topics, unfortunately nothing to do with what the OP really meant.

It is all enough to make me wonder, "How do we learn to write what we mean?"
