Start with what you want to do and work backwards to find your sources of information on making the project. There are lots of tutorials available on the internet through the magic of google. There are lots of books at libraries. But first you need to know all the topics you need. 

You mentioned making PCB boards. There are lots of tutorials on how to turn a schematic into a PCB board. But they require that you have a final circuit design that you want to convert before you start working on the PCB. They require that you know the size of the parts that you are going to be using. They require that you know what size box or enclosure you are going to have. They require that you know what other devices the PCB will need to connect to so that you can decide if plugs should go along the outside of the board. They require that you know how much power your parts will draw to determine the sizes of your traces. They require you to know whether you have any radio frequency elements. When you start the tutorial on making a PCB you will create a list of things you need to know that you don't know yet. Then work backwards to learn the answers to those questions.

After reading a tutorial, if you are missing any of the pieces....search for tutorials or books on the subject you are missing. 

In other words: "There is no simple step-by-step manual for solving every possible electronics problem easily". There are only manuals on small specific problems. You break your project into smaller and smaller problems until you get your list of books or tutorials.

Alternatively, if you want a free program that will build up from basic building blocks and work from start to finish of building a project...get the course list for an electrical engineering school and self-teach yourself the electrical engineering curriculum with books borrowed from the library. Of course, you might want to pay the tuition so that you can get a degree at the end of your studies.

And also let's not forget about https://www.nostarch.com/mg_electricity.htm

You can find out what textbooks a university or college is using for it's intro to electronics class and google around to see if you can find it online, or a previous edition.  Generally there are very few changes between editions.

There is no shortage of resources online for a beginner:

https://en.wikibooks.org/wiki/Microprocessor_Design

That's two topics in one and you'll need to learn the electronics side first.  For an absolute beginner, start with the something which gives you the basics, such as a Dummies Guide.  If that is enough for what you need then move to making boards.  If it's not, then I'd recommend the lab course by Horowitz which goes in to more detail with the Art of Electronics as a reference.  If that's still not enough, then you're in to specialist areas and specific texts - perhaps join forums for the application area you're looking at and ask for help when things get confusing.

For board design, YouTube is a great resource with loads of tutorials.  You may need to get technical if you're doing power, RF or high digital speeds (32MHz+) but for the most part PCBs are fairly forgiving.

I think adafruit is a good start for that.
