analog circuit design is different than anything in engineering and very different than anything in society either.
engineering school and society teach you to think in a straight line -- questions, formulas, solutions, everything is fast, instant messaging, computers, things are quick.
analog circuit design is like being an artist -- it takes a long time to learn, patience, discipline, love, intuition -- you just see things and know what happens, and that takes practice.
some people don't like the artistic part of analog design, the looking at the circuit, getting a feel for it, and being patience.
this is what it takes, finding different books, a lot of them, looking at different ways of looking at circuits, analog design is individual -- nobody can tell you how to be a good designer or how to learn it, everyone is different.
so, you need to do a lot of problems, see a lot of examples.
that is the best way.
