SunnySkyGuy, your story is impressive, but how does it help koen851? Koen851, it looks like you don't have the basic understanding of simple electronics (elements like resistors, capacitors, inductors, diodes and transistors and their combinations), therefore you have problems building your own circuits. Since you're young you lack some engineering school knowledge. If you can't gain nothing from the books, which is somehow strange (search for books with lots of circuits and their explanations), find yourself a mentor to guide you and/or ask specific questions on the net, like this board.
"So the sad thing was that I did it for a couple of years but I didn't really learn anything from it." If this is true, you're simply not interested in the how-it-works of electronics.
