Take a look at https://ultimateelectronicsbook.com/

It starts with fundamentals and includes in-browser circuit simulator to experiment with.

Once you have the fundamentals, something like "The Art of Electronics" by Horowitz and Hill is useful for rules of thumb and do's and don'ts of circuit design. Warning: this book by itself will not teach you enough fundamentals to be useful.

I'm going to take a look at the link. Thanks. I already found "The Art of Electronics" but it's too advanced for me right now.
