The title doesn't fully express what I'm asking here, because it doesn't allow enough room for my question. I know there are a lot of people here who have worked in a variety of fields outside of physics, without physics degrees, and I'm sure many of you have a large interest in physics. Have you actually gone and self studied higher level physics on your own? I ask that, because as an electrical engineering student, I can only take so many physics courses, while there's so much physics I want to learn. How do you even find time to learn about physics in your spare time when you actually have say, an engineering job? What do you do to learn about physics? And is it possible to learn a satisfactory (I know--subjective) amount of physics on top of a separate career and family life?
