Thank you!

I was just going to ask about recommended resources for getting into electronics. I've never been able to find anything that I personally found useful - often times, introductury courses are too basic and slow to keep me focused, or they lack exercises or are too theoretical, etc.

There are many hobbyists who have learned all that stuff and can design and implement their own circuits (say, audiophiles or model train enthusiasts), so obviously they have all been able to get there. But I have never managed to learn anything about electronics, although I would really like to.
