I just read your last reply, I'm going to post what I composed to say as Its been said already but just to let you know you are not alone in your feelings I have been there. here it is.
I think its good you have let us know how you feel about your electronics, I can only compare to my own journey with the subject, I have left a few times and know the frustration of getting equipment and components.
I have felt my understanding quiet basic when reading some of the depth of knowledge and understanding that is here on EEVBlog and the world in general. You can learn and I personally find it great to watch Dave and the forum members explain through their eyes and some times I go Ah thats cool, that makes sense I get it, and its enjoyable.
I have had some great enjoyment when I have experimented with stuff and built relatively simple op-amp circuits using a signal diode as a temperature sensor to make a thermometer and I got it to work, nothing more than a multimeter and few components simple DC, but fun.
Its taken me, a long time to get the basics and I'm happy to play with simple stuff now , I'm lucky to have a bit of space now at home and am getting a new work area together. Not like Daves lab, but he has been doing this for a long time.
Go slow you don't need to do it all at once is what I'm saying, I do sympathize, I know that feeling and I know when you buy components for a project they do cost a lot, it's all the little bits and bobs, I've been buying a 500 gram of solder expensive but it will last me a long time, I started out with little coils as a boy that was very expensive.
Stick to simple analog or basic digital circuits and experiment, put simple "Building blocks" together there is a lot of satisfaction to it when you get it to work and understand the circuit you have glued together, they have all been made before you learn from the people before.
The MIT course I would have liked in principle, but they have a very mathematical analytic approach that is not going to suit my level of mathematics or my way of seeing electronics.
Its not that you could not do it, you are not cleaver enough, but its a lot of work to get the familiarity and real understanding of what the math is showing to get the quickness and depth to be intuitive with the maths. Its not the only way to enjoy electronics I'm not building critical safety systems with legal responsibility to get it perfect.
Its no good for me I'm lazy with math I look at basic AC theory formulas and can get an idea what happens if this gets bigger, that gets smaller with time etc, I enjoy more the this switches that which pulls that high and starts this capacitor charging up, no math needed, not to much anyway !
I always seem to comeback to this "Electronics", I enjoy what I learn, i do not worry about what I do not know, personally I will never be anywhere near as refined as some of the pros on here, but thats fine, I enjoy what I do learn and play with.
You can enjoy simple circuits, they can be very tricky and interesting, look at the soft power switch circuit Dave is experimenting with, lots to think about there, not expensive to build , thats the sort of things you can get some fun learning with.
You are not alone with the costs and frustration of a workspace, its is hard to do practical work if you do not have a space to work. You can do a fair bit with a box of bits and a bread board but it is frustrating, I had a bench at the end of my bed but it used to frighten women away !, and my wife said not if you live with me, I have been there.
you can still enjoy Daves projects and all the fun here.I know some of what you are feeling, I have left and come back very recently myself.
It might not help how you are feeling now, but you can have fun without having a full lab and there are many levels to this game you do not need to understand the mathematics of quantum theory to picture an electron magically appearing on the other side of an insulator in a tunnel diode its still fascinating to read about and picture in your mind.
I think you know most of what I say already, you are just pissed of with all the restrictions you have at the moment I understand that, you are not on your own with that.
