I have always been interested in electronic circuits since 3rd grade when we lit a bulb up. I then always wanted to learn more and more. I'm a soft-more in high-school and it seems like i've it a dead end now. Every thing I build seems to break right after I get it to work and nothing seems to work right. I spend so much time tweaking one little thing just for failure over and over again. My whole room is just a pile of broken stuff that broke/could never get to work. I just seemed to reach a peak. I see a small, fairly simple electrical circuit and trust them that it works, but I don't get what's going on. I get a transistor amplifies but when I see a bunch together to make a circuit, I don't get it and my mind blanks out. I would hope to design my own circuits from ideas, but that I'm even farther. I do have a bunch of books, but those don't even seem to help. I really am passionate about electronic circuits and understanding how everything works but it just seems like my brain has reached a limit and I all of the sudden got stupid and unable to get any more information in there. I spend day after day working on my circuits but It just seems like I am digging on granite with a spoon.
What should I do next electronics wise to go up and increase my knowledge of electrical design? How can I keep my inspiration up and not give up ( it's really getting annoying having a 99% failure rate).
Thanks for any advice and I know this question will get closed, but I am really desperate for help.
