My rule of learning is:

I see and I forget. I hear and I remember. I do and I understand

The best way to learn how to do something is by doing it

Which honestly sounds like an oxymoron, but for instance, if you're wanting to learn electronics, the best way to learn electronics is to get a kit and assemble some electronics and learn about the parts as you're assembling them.

Or circuit design, you get a circuit sim software and design some circuits. Follow some schematics online.

Or, if you want to be a web developer, you spin up a server and start developing websites.
