The electronics sandbox is a pretty large place to play and folks have different interests.
For me, I need a project. The needs of the project will determine whether and where I might have to go to find more information. Google is full of projects.
OTOH, if you have an interest in 'circuits' for their own sake, "Learning The Art Of Electronics" just might be the best choice. It is a lab manual for "The Art Of Electronics" textbook and there are plenty of circuits to play with. You will probably need to be creative because the entire basket of parts is quite expensive. Not every experiment will be worth the cost. We used to call it 'pencil whipping' when we just calculated the results without building the project.
There are many web sites with electronics tutorials. EEVblog is one, of course, but a search on YouTube of 'w2aew' will turn up some great videos. w2aew has several videos on transistor circuits and these can be very helpful for beginners learning about amplifiers. Plan to spend some time on those playlists. Detailed explanations are the reason I like his videos. Very professional!
I hesitate to suggest other textbooks because they usually have a very pedantic approach to electronics and it usually includes more theory and math than a hobbyist might need. It takes too long to get anywhere, frankly, it can get boring.
If you do want a more 'engineering' approach, consider Khan Academy as a start. They have an EE program as well as a gigantic math program.
Digilent has a "Real Analog" program that combines lectures with labs. I have watched some of the lectures and, once again, they are heavy on the theory of electronics (as you would expect) and I haven't worked through the labs.
