Get a good book on basic circuit analysis, and start learning a solid
theoretical background. Ultimately that will be the only way to make
sense of the real deal behind most moderate to highly sophisticated
circuits, including a simple op-amp. You will be able to understand the
DC gain of an op-amp within a few hours of reading, experimenting, and
basic algebra. Then to understand the AC behavior of the op-amp, take
several semesters of calculus, then you will have the tools to
understand that. Often you will try to make a circuit that seems very
simple, but the quirks can only be understood by having the solid
engineering math and theory background.
Just ask around and find out how many people think that a long
transmission line somehow loads a driver differently than a short one,
But couple that with a lot of tinkering. Make electronics your hobby,
and get a job in it if you wish, once you have the skills needed to get
