Learning physics is not the same as learning to do physics. If you want to learn how to really do it, you need to work problems.
This means you to learn the techniques, and you need problem books, with solved examples, that you can work through on your own, or with a small group. This is absolutely critical. This includes both complex mathematical calculations as well as back-of-the-envelope calculations.
Moreover, while textbooks are great references, nothing replaces a good video lecture or presentation, that gets to the heart of the physical concepts without being overly technical. n
And remember that physics is fundamentally an experimental science. It is not just advanced mathematics. Even if you yourself are not an experimentalist, you need to understand the basics.
I should mention that "good video lectures" are extremely hard to come by. Experts appreciate a clean narrated delivery, and novices like it too, but students generally don't learn from a monologue.
You can't just watch videos. You have to work through the problems.
The right sort of textbook is just as good as a good lecture.
In math, books like Rudin's Principles of Analysis are extremely thorough, rigorous, and a great source of problems, but not a good book to start learning from. On the other hand, Abbott's Analysis is a less detailed book but a much better introduction. Any textbook that takes itself too seriously is probably not going to be as good as a lecture.
