I know a good number of people who seem to be able to self study physics material - aka read ahead for classes, read textbooks outside of classes, and I always find myself jealous. I'm usually able to learn pretty well on my own if I have a project, or if I'm trying to learn something really specific, but I can feel that I never approach the same level and scope as learning from a class. If I try to read a textbook, I get bored after 2 or 3 chapters, even if it is a topic that I was really interested in. And I rarely motivate myself to do more than a couple practice problems. In other words, usually it's either that I'm interested starting out in the book but it's really hard to focus once I've gotten the gist of the explanation or I'll read the couple of chapters that are particularly interesting then stop. Does anyone else have the same issue? How do you motivate yourself to keep reading or focus? or does it just come naturally to you if you are interested in a topic? Do you care about learning on your own? I'm thinking specifically of physics-type material books, although my question could apply to anything.
